Perovskites nanogels: synthesis, properties and applications
Metal halide perovskite nanogels have recently arisen as a new frontier in material science and have drawn worldwide attention for various promising applications, involving photovoltaics, light-emitting diode, lasing, photodetector, sensing and imaging. Their optical, excitonic, optoelectronic, and charge transport properties could be finely tuned through changing the crystal composition and structure, doping with other metal-ions, and employing diverse synthetic approaches for different morphologies. In this review, we focus on recent progress in wet-chemistry synthetic methods for perovskite nanogels with typical morphologies. Specifically, the synthesis of nanocubes, nanowires, nanoplatelets and microdisks are discussed in detail. Moreover, the lead-free perovskite nanogels are also summarized. Furthermore, the latest progress in promising applications of perovskite nanogels is also described. Finally, based on the deep understanding of the mechanism of perovskite-related devices, the outlook for future research and main challenges of perovskite nanogels are further addressed.
