Ease of synthesis, tunable bandgaps, and high emission quantum yield of chemically synthesized metal halide perovskite nanocrystals make this class of materials particular attractive for applications in photovoltaics and optoelectronics [1]. In this talk, I will introduce some of our recent synthetic strategies leading to stable, strongly luminescent hybrid perovskite based nanomaterials, and provide examples of their use in light-emitting devices [2], solar cells [3], photodetectors [4], and digital microfluidics [5].
