제목 Prototype LEDs application of Highly Robust Flexibility and Luminescence Nature of Perovskite Crystal Embedded Al2O3-La2O3 Nanofibers Membrane
초록 The development of extremely flexible inorganic luminescence materials is one of the major problems because of their use of practical implementation is greatly hindered by the intrinsic brittle nature. Here we have synthesized flexible Al2O3-La2O3 (CCAL) nanofibrous membranes assisted on CsPbBr3/Cs4PbBr6 perovskite crystals by facile electrospinning and successive supersaturated recrystallization process. The as-prepared materials demonstrate outstanding mechanical flexibility and characteristic of luminescence. Meanwhile, molar ratios of CsBr/PbBr2 differ in the crystal structure and luminous performance of the CCAL membranes, and the optimal CsBr/PbBr2 ratio of 1 is regulated and has exhibited a narrow emission linewidth of 18 nm and reaches a maximum photoluminescence value. In addition, the CCAL nanofibrous membranes have been proved for potential application in green light devices through a remote nanofibrous membranes packaging strategy.
