Halide perovskite nanocrystals have attracted a great amount of research attention due to their unique optoelectronic properties, leading to a range of potential applications including light emitters, displays, X-ray imaging and solar energy harvesting. In this context, lead-free halide perovskite and perovskite-analogue nanocrystals have emerged as a new category of materials that hold the potential for overcoming the instability and toxicity issues of lead-based counterparts. In this talk, I will discuss some of our recent studies about synthesis, characterization and application of different lead-free halide perovskite and perovskite-analogue nanocrystals. I will focus my talk on crystal phase control, composition and structure tuning, and applications of this special category of materials. Both experimental data and first-principal Density Functional Theory calculation results will be included in the talk.
