recommendations! Published in 2019 at "Ceramics International"

DOI: 10.1016/j.ceramint.2018.12.038

Abstract: Abstract Perovskite-based Cs4PbBr6 has potential applications in optoelectronic devices, such as photodetectors, electroluminescence devices and color converters. All-inorganic perovskite Cs4PbBr6 thin films were successfully prepared by a simple low-temperature synthesis method and were first implemented… read more here.
