Cesium lead halide perovskite nanocrystals have generated a significant interest in the field of optoelectronics due to their easily tunable band gap that spreads across the visible spectrum when their halide character is varied. However, the presence of lead in these materials have limited their wide spread commercial use because of concerns over the toxicity. Replacing the lead with tin has been one direction that is gaining popularity. In my research, I will be working on optimizing the synthesis of cesium tin halide nanocrystals for use as host lattices for transition metal dopants such as rhenium. This research would add foundational knowledge to the understanding of electronic processes and synthesis of these materials which have only just begun to be investigated in the field.
