Development of perovskite-based light emitting diodes with improved stability
Inorganic cesium lead halide (CsPbX3) perovskite nanocrystals (NCs) are promising materials for many applications in optoelectronics due to their good photophysical properties compared to hybrid perovskites. As a result, many methods of synthesizing these NCs have been invented. In this project, we...

| Summary: | Inorganic cesium lead halide (CsPbX3) perovskite nanocrystals (NCs) are promising materials for many applications in optoelectronics due to their good photophysical properties compared to hybrid perovskites. As a result, many methods of synthesizing these NCs have been invented. In this project, we aim to develop perovskite NCs that have high stability and high photoluminescence quantum yield (PLQY). The methods that are being explored in this report are Hot-Injection Process, Room-Temperature Synthesis and Microwave Irradiation. It is found that by replacing the ligands involved in the Microwave Irradiation method, it is possible to have better stability which is measured by higher yield. |
