Article Citation - WoS: 2Citation - Scopus: 1Fully Inorganic Colloidal CsPbBr3 Perovskite Nanocrystals with Zn-Doping and Metal Oxide Encapsulation for Luminescent Display Panels(Amer Chemical Soc, 2025-11-07) Khorasani, Azam; Soheyli, Ehsan; Mutlugun, EvrenPerovskite nanocrystals (PeNCs) are emerging as exceptional materials due to their high photoluminescence quantum yield, tunable bandgap, and excellent charge carrier mobility, enabling a wide range of colors and promising applications in optoelectronics and photovoltaics. Despite their advantages, PeNCs face stability challenges caused by environmental factors. In the presented study, a facile and versatile colloidal hot-injection method was used to apply the beneficial aspects of Zn-doping in cesium lead bromide (CsPbBr3) PeNCs. The uniform platelet-shaped Zn-doped CsPbBr3 PeNCs were prepared by doping with a 0.1 molar ratio of zinc-oleate solution in the perovskite precursors during synthesis. Then, zinc-oxide (ZnO) and nickel-oxide (NiO) coating layers were utilized separately to effectively reduce surface defects, encapsulate PeNCs, and improve their stability issues. To fabricate the coated PeNCs with metal oxides, zinc acetate and nickel(II) acetate tetrahydrate solutions were prepared individually and added to the crude perovskite solutions. The quantum yield of Zn-doped CsPbBr3 (CsPb1-xZnxBr3) PeNCs coated with ZnO increased from 50% for bare CsPbBr3 to over 84%, while NiO-coated PeNCs exhibited a higher yield of 90% both of which remarkably enhanced the emission stability. Moreover, NiO coatings represented a proper protection against surface imperfections and improved resistance to external stimuli. The combination of facile/effective preparation method, excellent emission efficiency, and reliable emission stability nominates the prepared colloidal composite for display pixels, detectors, and lasers.Conference Object Selective Dye Uptake From Aqueous Industrial Waste Mixtures by Novel Covalent Organic Frameworks(Amer Chemical Soc, 2015) Filikci, Semra; Ulasan, Mehmet; Citir, Murat; Yavuz, MustafaConference Object Removal of Organic Solvents From Aqueous Waste Mixtures by Novel Covalent Organic Frameworks(Amer Chemical Soc, 2015) Ulasan, Mehmet; Filikci, Semra; Citir, Murat; Yavuz, MustafaConference Object Polymeric Semiconductors Based on Meso-Substituted BODIPY for (Opto)electronic Applications(Amer Chemical Soc, 2019) Usta, Hakan; Kim, Choongik; Kim, BumjoonConference Object Photophysical Properties of Self-Assembled Supramolecular Peptide Nanofiber Organic Semiconductors(Amer Chemical Soc, 2015) Khalily, Mohammad Aref; Usta, Hakan; Guler, Mustafa O.Conference Object Organic Semiconductor Based Surface-Enhanced Raman Spectroscopy Platforms(Amer Chemical Soc, 2018) Demirel, Gokhan; Usta, Hakan; Facchetti, AntonioConference Object Novel Photothermal-Based Release Mechanism for Controlled Release on Au Nanoparticles Through Light(Amer Chemical Soc, 2015) Goren, Ekrem; Cavusoglu, Halit; Yavuz, Emine; Usta, Hakan; Yavuz, Mustafa SelmanConference Object New Method for Measuring the Temperature Change of Photothermal Au Nanostructures Using Smart Polymers(Amer Chemical Soc, 2015) Cavusoglu, Halit; Sakalak, Huseyin; Buyukbekar, Burak Zafer; Demirel, Gokhan; Citir, Murat; Yavuz, Mustafa SelmanConference Object Nanothermometer: Measuring Temperature Change in Nanometer Scale on Photothermal Au Nanoparticles(Amer Chemical Soc, 2015) Sakalak, Huseyin; Cavusoglu, Halit; Buyukbekar, Burak Zafer; Demirel, Gokhan; Citir, Murat; Yavuz, Mustafa SelmanConference Object Nanostructured Superhydrophobic Organic Semiconductor Films Enable Sub-Zeptomole Level Molecular Sensing in Surface-Enhanced Raman Spectroscopy(Amer Chemical Soc, 2017) Demirel, Gokhan; Usta, Hakan; Facchetti, Antonio
