Lead halide perovskites (LHPs) of the general formula APbX3 (A=Cs+, CH3NH3+, or CH(NH2)2+; X=Cl, Br, or I) have recently emerged as a unique class of low-cost, versatile semiconductors of high optoelectronic quality. These materials offer exceptionally facile solution-based engineerability in the form of bulk single crystals, thin films, or supported and unsupported nanostructures. The lattermost form, especially as colloidal nanocrystals (NCs), holds great promise as a versatile photonic source, operated via bright photoluminescence (PL) in displays or lighting (energy down-conversion of blue light into green and red), or via electroluminescence in light-emitting diodes. In this article we discuss the recent history of the development of highly-luminescent NCs of LHPs, the current state-of-the-art of this class of materials, and the future prospects of this highly active research field. We also report the demonstration of long-range ordered, self-organized superlattice structures obtained from cube-shaped colloidal CsPbBr3NCs using drying-mediated self-assembly.
