| 요약 | This dissertation is a broad overview of research in the field of lead-free perovskite inspired materials. While lead halide perovskites have promising properties, we sought to investigate non-toxic alternatives - typically ones containing bismuth halides. We looked into the flexibility of this element to be produced on different length scales, fabricating films from bulk material, synthesizing nanocrystals, and growing crystals of 2D layered double perovskites. We discovered that due to complexation with a solvent, bismuth iodide films can be morphology controlled through use of solvent additives. During our synthesis of Cs3Bi2X9 nanocrystals, we found that BiX3 precursors possessed photoluminescence and that treatment of these seeds was crucial to the end product of the reaction. We investigate layered double perovskites containing bismuth and found that these materials have a structural transition and a thermochromic behavior. Further, we determine that these double perovskites can be processed into nanocrystals through sonication. Finally, we investigated the aforementioned Bi seeds to determine methods of controlling the morphology and processability of the seeds, finding that changing an alkylammonium ligand helps direct some amount of self-assembly. We conclude that bismuth based materials have many interesting properties that encourage future investigation into bismuth halides. |
