研究目的
Investigating the non-radiative recombination processes in organo metal halide perovskites using photoluminescence microscopy to understand the dynamics and chemical nature of non-radiative centres.
研究成果
The study provides insights into the non-radiative recombination processes in organo metal halide perovskites, highlighting the role of individual non-radiative channels and their dynamics. It suggests that the temperature activation of PL quenching is related to potential barriers in charge carrier diffusion and trapping, offering a pathway for future research to optimize these materials for optoelectronic applications.
研究不足
The study is limited by the dynamic and inhomogeneous nature of the perovskite materials, which complicates the understanding of non-radiative recombination processes.
