Halide perovskite nanocrystals: Synthesis, properties and applications
This review summarized the recent developments in the field of halide perovskite nanocrystals (NCs) and their derivatives. The synthetic methods of these perovskite NCs, as well as their optical properties, structural modification and applications have been discussed. Despite the significant progress achieved in perovskite nanostructures, challenges regarding to their long-term stability, inferior charger transport features, and lead-content still need to be addressed. Proper surface modification is a possible approach to obtain NCs with both excellent conductivity and stability. Besides, more practical works need to be done to explore environmentally benign lead-free NCs, with excellent electronic properties.
