Abstract
In recent years, metal halide perovskites have been demonstrated to be a promising class of materials for optoelectronic applications, including high-efficiency solar cells, light emitting diodes, lasers, and photodetectors. Among metal halide perovskites, all-inorganic cesium lead halide perovskites CsPbX3 (X= Cl, Br, I) have attracted particular attention due to enhanced stability compared to their analogue organic-inorganic hybrid perovskites. Very recently, CsPbX3 nanostructures such as nanoparticles, nanoplates and nanorods have been increasingly explored. Thanks to the quantum confinement effect, these nanostructured CsPbX3 exhibit excellent optical properties. However, the photophysics behind nanostructured CsPbX3 is very complicated and still far from full understanding. In this PhD degree research, we aim at deepening our understanding of photophysics behind nanostructured CsPbX3 perovskites via investigating light scattering, temperature-dependent steady-state and time-resolved photoluminescence (PL) in nanostructured CsPbX3. Already obtained preliminary results are very encouraging, which will be presented in this presentation. Further study plan and expectations will be also discussed.
