CsPbX3 nanocrystals exhibit superior optoelectronic properties by providing wide photoluminescent quantum efficiency (PLQY), wide emission spectrum tunability and short luminescence lifetime. It is also a material that can make new optoelectronic devices such as light emitting diodes (LEDs) and solar cell. Hybrid organic-inorganic halide perovskite materials are semiconductors with good performance in LED manufacturing, but lead-containing materials are not stable. This has led to the need for non-lead perovskite materials with similar photoelectric properties The synthesized [((R) - C8H12N) 4] [Bi2I10] LEDs showed bright green luminescence with current efficiency and external quantum efficiency of 9.22 cd/A and 2.64%, respectively. The generated LEDs showed green emission with a maximum luminance of 502.96 cd/m2 and a current efficiency of 0.29 cd/A. Finally, Bi-perovskite is a non-lead perovskite, which is able to solve the environmental and stability problems of CsPbX3 nanocrystals. |
