Halide perovskite semiconductors can merge the highly efficient operational principles of conventional inorganic semiconductors with the low‑temperature solution processability of emerging organic and hybrid materials, offering a promising route towards cheaply generating electricity as well as light. Following a surge of interest in this class of materials, research on halide perovskite nanocrystals (NCs) has gathered momentum in the last decade. This talk will highlight several findings of our group on their synthesis, for example our recent study on the influence of various exogenous cations and acid-based equilibria on the growth of perovskite NCs, and the preparation of NCs in the strong quantum confinement regime. Superstructures of perovskite nanocrystals are also capturing the attention of the community, for example for what concerns their superfluorescence. I will discuss our findings on the ordering of nanocrystals in superstructures, especially on how this is related to the specific surface ligands and how it influences exciton diffusion processes.
