Abstract



Perovskite nanocrystals are of enormous interest for material science and applications including solar cells and light-emitting diodes due to precise tunability of their properties via size and shape. Accordingly, various synthetic methods have been proposed, but achieving monodispersed nanocrystals remains a key challenge leading to the present lack of their commercial value and real-world applications. In this presentation, I will present how unique features of liquid crystals can be leveraged to synthesize nanocrystals with an unprecedented level of control over size and shape. The approach is a simple, rapid, and room-temperature process, yet it enables access to highly homogeneous nanocrystals with substantially reduced surface defects resulting in significantly improved optoelectronic features. The results offer a versatile and generalizable strategy to be broadly compatible with a range of nanomaterials and other synthetic methods.
