    High-Efficiency Light-Emitting Diodes of Organometal Halide Perovskite Amorphous Nanoparticles by Xing, Jun, Yan, Fei, Zhao, Yawen, Chen, Shi, Yu, Huakang, Zhang, Qing, Zeng, Rongguang, Demir, Hilmi Volkan, Sun, Xiaowei, Huan, Alfred, Xiong, Qihua

    Published 2017
    “…Herein, we propose and demonstrate facile solution synthesis of a series of colloidal organometal halide perovskite CH3NH3PbX3 (X = halides) nanoparticles with amorphous structure, which exhibit high quantum yield and tunable emission from ultraviolet to near-infrared. The growth mechanism and photoluminescence properties of the perovskite amorphous nanoparticles were studied in detail. …”
