[Th-P-30]Excitonic Relaxation Process of CsPbBr3 Perovskite Nanocrystals
〇FANCHUN WEI1, Takuma Tanitsu1, Sekika Yamamoto1 (1. Hokkaido Univ. (Japan))
Excitonic relaxation in CsPbBr3 perovskite nanocrystals is investigated by temperature-dependent photoluminescence decay. kslow follows a two-phonon interaction model, while kfast decreases with temperature. The initial population ratio indicates non-random hot-exciton relaxation.
