| Outline of Final Research Achievements |
Organic-inorganic halide perovskites show excellent photophysical properties and are attracting attention as materials for next-generation optical and electronic devices such as light-emitting diodes and displays. In this study, we aimed at elucidating the fundamental photophysical properties of perovskite nanocrystals using single particle spectroscopy. The main results include clarification of the electroluminescence blinking phenomenon and electroluminescence efficiency by simultaneous measurement of electroluminescence and photoluminescence in CsPbBr3 perovskite nanocrystals, suppression of the blinking of perovskite nanocrystals by ligand exchange, and elucidation of the nanocrystal formation process and ion diffusion in halide perovskite-metal organic framework composite materials.
