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 colloidal 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 studies on the influence of various factors on the growth of perovskite NCs, which can lead to the formation of NCs with peculiar shapes (for example hollow structures) and to NC heterostructures by promoting/suppressing the heterogenous nucleation of selected materials. We will highlight several cases of core-shell heterostructures prepared by partial halide or B cation exchange. Detailed structural and optical investigations of these heterostructures will be covered, and their potential in a set of photocatalytic reactions and in light emitting devices will be discussed.
