Conference Object Enhanced Photoluminescence From Quantum Emitter-Nanoplasmonic Antenna Hybridization by a Facile Fabrication Method(IEEE, 2024) Genc, Sinan; Yilmaz, Alpay; Fernandez, Carlos Rodriguez; Caglayan, Humeyra; Bek, AlpanGaps between tiny metallic nanostructures create strong local fields and small mode volumes, known as hybrid plasmonic modes. This study introduces a nanocavity formed by silver nanoparticles on a gold substrate with hexagonal boron nitride flakes, boosting quantum emitters' spontaneous emission and photoluminescence yield.Conference Object Citation - Scopus: 1Color Simulation and Demonstration of Perovskite Nanocrystal Filters for Wide Color Gamut Displays(Institute of Electrical and Electronics Engineers Inc., 2018) Genc, Sinan; Yazici, Ahmet F.; Beskazak, Emre; Uran, Can; Mutlugün, EvrenIn this study, we define spectral parameters of perovskite nanocrystals to improve LCD color gamut, replacing color filters (CFs) with perovskite based subpixels. The optimization of the CFs has been enhanced 15.8% (98.43% of Rec.2020) in simulation and 13.8% experimentally, with 97.37% color gamut coverage. © 2019 Elsevier B.V., All rights reserved.Article Citation - WoS: 11Citation - Scopus: 10Trans-Cis Isomerization Assisted Synthesis of Solution-Processable Yellow Fluorescent Maleic Anhydrides for White-Light Generation(Elsevier Science SA, 2015) Ozdemir, Mehmet; Genc, Sinan; Ozdemir, Resul; Altintas, Yemliha; Citir, Murat; Sen, Unal; Usta, HakanHeterocyclic maleic anhydride derivatives have been extensively studied in natural products chemistry over the past few decades. However, their incorporation into optoelectronic devices has lagged behind that of other pi-conjugated systems, and they have never been studied in white light emitting diodes (WLEDs). The development of emissive pi-conjugated materials for (WLEDs) has been an emerging scientific and technological research area to replace phosphors used in LED-based solid-state lighting. Here, we demonstrate the design, synthesis and characterization of two new highly emissive alkyl-substituted bis(thienyl)maleic anhydrides (C6-Th2MA and C12-Th2MA) with favorable photophysical properties. The new core is synthesized via a novel trans-to-cis isomerization-assisted one-pot reaction, which is demonstrated for the first time in the literature for the synthesis of a bis(heteroaryl)maleic anhydride. Due to its favorable absorption and fluorescence properties in the blue and yellow region of the visible spectrum, respectively, C12-Th2MA is studied as a potential wavelength-upconverting material. A WLED fabricated by drop-casting a polymeric solution of C12-Th2MA on a blue LED (InGaN, 455 nm) yields promising CIE coordinates and color-rendering index (CRI) values of (0.24, 0.20) and 65.0, respectively. Considering the simplicity of the current molecular structure and facile synthesis, alkyl-substituted bis(thienyl)maleic anhydrides stand as ideal phosphor alternatives. Therefore, the current findings may open new perspectives for the development of maleic anhydride-based small molecules for low-cost, energy-efficient, and solution-processed lighting technologies.

Due to the complexity of Mie scattering theory, the features of the scattered light have rarely been related to the physical properties of these tiny objects. To address this problem, we reveal the relation of the wavelength-dependent optical scattering patterns with the size and refractive index of the particles by numerically studying the angular scattering features. We subsequently present a low-cost setup to measure the optical scattering of the particles. Theoretical investigation shows that the angular distribution of the scattered light by microplastics carries distinct signatures of the particle size and the refractive index. The results can be used to develop a portable, low-cost setup to detect microplastics in water.Article Citation - WoS: 4Citation - Scopus: 4Rec. 2100 Color Gamut Revelation Using Spectrally Ultranarrow Emitters(SPIE - Society of Photo-Optical Instrumentation Engineers, 2017) Genc, Sinan; Uguz, Mustafa; Yilmaz, Osman; Mutlugun, EvrenWe theoretically simulate the performance of ultranarrow emitters for the first time to achieve record high coverage for the International Telecommunication Union Radiocommunication Sector BT. 2100 (Rec. 2100) and National Television System Committee (NTSC) color gamut. Our results, employing more than 130-m parameter sets, include the investigation into peak emission wavelength and full width at half maximum (FWHM) values for three primaries that show ultranarrow emitters, i.e., nanoplatelets are potentially promising materials to fully cover the Rec. 2100 color gamut. Using ultranarrow emitters having FWHM as low as 6 nm can provide the ability to attain 99.7% coverage area of the Rec. 2100 color gamut as well as increasing the NTSC triangle to 133.7% with full coverage. The parameter set that provides possibility to fully reach Rec. 2100 also has been shown to match with D65 white light by making use of the correct combination of those three primaries. Furthermore, we investigate the effect of the fourth color component on the CIE 1931 color space without sacrificing the achieved coverage percentages. The investigation into the fourth color component, cyan, is shown for the first time to enhance the Rec. 2100 gamut area to 127.7% with 99.9% coverage. The fourth color component also provides an NTSC coverage ratio of 171.5%. The investigation into the potential of emitters with ultranarrow emission bandwidth holds great promise for future display applications. (C) 2017 Society of Photo-Optical Instrumentation Engineers (SPIE)Master Thesis Verimli Aydınlatma ve Ekran Teknolojileri için Fotometrik Modellemelerin Gerçekleştirilmesi(Abdullah Gül Üniversitesi, 2016) GENÇ, SİNAN; Genç, Sinan; Mutlugün, EvrenAydınlatma elemanı olarak ışık saçan diyotların (LED) kullanımı, enerji verimliliği bağlamında zorunlu bir adım olarak ortaya çıkmıştır. Dünya çapında üretilen toplam enerjinin yaklaşık %25'i aydınlatma için kullanılmaktadır. Akkor telli ampullerin aydınlatma elemanı olarak kullanılması Avrupa'nın büyük bir kısmında yasaklanmış ve ışık saçan diyotlar en popüler seçenek olarak bu açığı doldurmuştur. Hem aydınlatma seviyesi hem de enerji verimliliği açısından yüksek performanslı oluşları, daha verimli hale getirilebilmeleri için yeni bir araştırma alanı ortaya çıkarmıştır. Yüksek kaliteli beyaz ışık kullanıldığı ortama göre farklı özellikler gerektirir ve beyaz ışığı oluşturan renk bileşenlerini optimize ederek bu gerekliliklerin sağlanması, bu tezin temel amaçlarından biridir. Ekran teknolojisinde, tüplü televizyonlardan (CRT), organic ışık saçan diyot (OLED) ürünlere gelişme süreci, hem ekran kalitesi hem de enerji verimliliği performansını arttırmıştır. Ekranlardaki renk skalasının, insan gözüyle algılanabilen skalaya doğru genişlemesi temel amaç olduğundan, referans alınan skala sistematik bir şekilde genişlemektedir. Literatürdeki son referans, Rec.2020, insan gözüyle algılanabilen renklerin üçte ikisini kapsamaktadır. Bu tezde, kullanımda olan NTSC renk skalası gibi referanslar da dikkate alınarak Rec.2020 renk gamının genişletilmesi yeni bir amaç olarak tanımlanmıştır. Bu tezde, istenilen kalitedeki beyaz ışığa ulaşabilmek için, renk bileşenlerinin tepe ışıma dalga boyu, ışıma genişliği ve tepe değeri gibi ışıyıcı parametrelerinin sahip olması gereken değerler araştırılmıştır. Her adımda beyaz ışık elde edilmesine rağmen, dört renk bileşeni ile oluşturulan beyaz ışık simülasyonu yüksek kaliteli beyaz ışık gereklilikleri olan renk eşleme indisi >90, renk sıcaklığı <4000K ve optik yayılmanın ışıksal verimi >380lm/Wopt değerlerini aynı anda sağlamıştır. Ek olarak, ekran teknolojisi bağlamında, Rec.2020 renk referansına ulaşabilmek için kolloidal kuantum noktacıklar gibi dar ışıyıcılar ile birlikte 10nm'den daha dar (ultra dar) ışıyıcıların da kullanılmasının uygunluğu belirtilmiştir. Ultra dar ışıyıcılar ile Rec.2020 üçgeninin %99.89'una ulaşılmış ve bu parametreler kullanılarak NTSC referansı da %99,99'dan daha büyük yüzde ile kapsanmıştır. Beklenildiği üzere, dördüncü renk olarak siyan mavisinin kullanılması NTSC referansına göre ulaşılabilen alanı %169,55'ye çıkarmıştır.Doctoral Thesis Optik Saçılma Temelli Rastgele Orman Destekli Parçacık Tespiti ve Sınıflandırılması(Abdullah Gül Üniversitesi / Fen Bilimleri Enstitüsü, 2023) Genç, Sinan; Genç, Sinan; İçöz, Kutay; Erdem, TalhaMicroplastics, tiny plastic particles with sizes smaller than 5 mm., are often found in oceans, rivers, lakes, and atmosphere due to plastic pollution. Microplastics releasing toxic chemicals threaten the environment and harm the aquatic life and humans. Especially, the accumulation of microplastics can have detrimental effects on the food chain as a result of larger organisms consuming smaller organisms. Detecting the microplastics is crucial but also challenging. Over the years, researchers have developed different detection methods. One of the standard methods is using spectroscopy tools such as Fourier transform infrared spectroscopy (FTIR) and Raman spectroscopy. These techniques can identify the chemical composition of microplastics, which can help determine their sources and potential impacts. Another method is the use of microscopy, which allows for the visualization and counting of microplastics in samples. However, these techniques require costly infrastructure, and these instruments being large in size significantly limits the mobility. As a remedy to the cost and mobility problems, in this thesis, we propose and demonstrate a low-cost, portable system to detect size, concentration, and refractive index of microplastics. Our system comprises of low-cost and low-weight components which are utilized for recording the scattering patterns of microplastics in aqueous media. We demonstrate successful predictions of the size and refractive index of microparticles at a given wavelength using a Random Forest Algorithm which relates the measured scattering pattern with the Mie theory. We further employ the refractive index information at various wavelengths for determining the material type of microplastics. We believe that our proposed system enabling an easy, fast, low-cost, and on-site detection of microplastics will be a beneficial tool for the fight against microplastics in the environment.Conference Object Low-Cost SERS Substrates via AuNP-Decorated Carbonized Polyimide Films for Fluorescence-Quenched Raman Sensing(Institute of Electrical and Electronics Engineers Inc., 2025) Tuzel, D.; Cinar, K.; Bek, A.; Khan, G.A.; Kina, S.; Genc, S.Article Citation - WoS: 15Citation - Scopus: 18FRET Enabled Light Harvesting within Quantum Dot Loaded Nanofibers(IOP Publishing Ltd, 2018) Altintas, Yemliha; Kiremitler, Nuri Burak; Genc, Sinan; Onses, M. Serdar; Mutlugun, EvrenThe spatial control of the nano-emitters in novel light harvesting platforms offers great potential for the manipulation of the excitonic interaction amongst the donor-acceptor pairs of energy transferring agents. In this work, we report colloidal quantum dot loaded electrospun nanofibers as a light harvesting platform to study the excitonic interaction among them. The donor emission lifetime modified from 12.46 ns to 7.45 ns with the change in the ratio of green and red quantum dots in the nanofiber, as a result of confining acceptor quantum dots in close proximity. The spectrally narrow emitter luminescent nanofiber platforms have further been investigated for their potential of white light generation. The hybrid platform of blue LED integrated electrospun nanofibers has been shown to demonstrate a correlated color temperature of 3632.5 K, luminous efficacy of optical radiation value of 307.7 lm/W-opt along with color rendering index value of 60.Article Disorder-Engineered Hybrid Plasmonic Cavities for Emission Control of Defects in HBN(American Chemical Society, 2026) Genc, Sinan; Yucel, Oguzhan; Aglarci, Furkan; Rodriguez-Fernandez, Carlos; Yilmaz, Alpay; Caglayan, Humeyra; Bek, AlpanDefect-based quantum emitters in hexagonal boron nitride (hBN) are promising building blocks for scalable quantum photonics due to their stable single-photon emission at room temperature. However, enhancing their emission intensity and controlling the decay dynamics remain significant challenges. This study demonstrates a low-cost, scalable fabrication approach to integrate plasmonic nanocavities with defect-based quantum emitters in hBN nanoflakes. Using the thermal dewetting process, we realize two distinct configurations: stochastic Ag nanoparticles (AgNPs) on hBN flakes and hybrid plasmonic nanocavities formed by AgNPs on top of hBN flakes supported on gold/silicon dioxide (Au/SiO2) substrates. While AgNPs on bare hBN yield up to a 2-fold photoluminescence (PL) enhancement with reduced emitter lifetimes, the hybrid nanocavity architecture provides a dramatic, up to 100-fold PL enhancement and improved uniformity across multiple emitters, all without requiring deterministic positioning. Finite-difference time-domain (FDTD) simulations and time-resolved PL measurements confirm size-dependent control over decay dynamics and cavity-emitter interactions. Our versatile solution overcomes key quantum photonic device development challenges, including material integration, emission intensity optimization, and spectral multiplexity.
