    Highly Flexible, Electrically Driven, Top-Emitting, Quantum Dot Light-Emitting Stickers
    (American Chemical Society, 2014-07-18) Yang, Xuyong; Mutlugün, Evren; Dang, Cuong H.; Dev, Kapil; Gao, Yuan; Tan, Swee Tiam; Volkan Demir, Hilmi Volkan; Demir, Hilmi Volkan
    Flexible information displays are key elements in future optoelectronic devices. Quantum dot light-emitting diodes (QLEDs) with advantages in color quality, stability, and cost-effectiveness are emerging as a candidate for single-material, full color light sources. Despite the recent advances in QLED technology, making high-performance flexible QLEDs still remains a big challenge due to limited choices of proper materials and device architectures as well as poor mechanical stability. Here, we show highly efficient, large-area QLED tapes emitting in red, green, and blue (RGB) colors with top-emitting design and polyimide tapes as flexible substrates. The brightness and quantum efficiency are 20 000 cd/m2 and 4.03%, respectively, the highest values reported for flexible QLEDs. Besides the excellent electroluminescence performance, these QLED films are highly flexible and mechanically robust to use as electrically driven light-emitting stickers by placing on or removing from any curved surface, facilitating versatile LED applications. Our QLED tapes present a step toward practical quantum dot based platforms for high-performance flexible displays and solid-state lighting. © 2014 American Chemical Society. © 2021 Elsevier B.V., All rights reserved.

    Color Simulation and Demonstration of Perovskite Nanocrystal Filters for Wide Color Gamut Displays
    (Institute of Electrical and Electronics Engineers Inc., 2018-09) Genc, Sinan; Yazici, Ahmet F.; Beskazak, Emre; Uran, Can; Mutlugün, Evren
    In 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.

    Arrays of Multi-Color Emitting Cesium Lead Halide Perovskite Nanocrystals and Efficient White Light Generation by Tailored Anion Exchange Reactions and Electrohydrodynamic Jet Printing
    (Optica Publishing Group (Formerly OSA), 2018) Altıntas, Yemliha; Torun, Ilker; Yazici, Ahmet F.; Beskazak, Emre; Onses, Mustafa Serdar; Mutlugün, Evren
    We employ highly efficient and narrow band emitter Cesium-lead-halide perovskite nanocrystals, optimized by the anion exchange method, for efficient white light generation by patterning multiple lines of different colors via proposed electrohydrodynamic jet printing. © 2023 Elsevier B.V., All rights reserved.
