(765e) Solution-Based Synthesis of Cesium Bismuth Halide Perovskite Nanocrystals for Optoelectronic Applications
This work reports the synthesis of cesium bismuth halide perovskite nanocrystals using solution-based methods. The Bi-perovskite nanocrystals show improved phase-stability compared to Pb-based perovskite nanocrystals. Transmission electron microscopy and X-ray diffraction were used to characterize nanoparticle morphology and crystal structure. Absorbance and photoluminescence measurements of these nanocrystals reveal tunable optical properties. These Bi-based perovskite nanocrystals have potential for high performance, stable, and non-toxic solution-processable optoelectronics.
