Up-Conversion Films and Polymer Matrices with CsPbBr3 Perovskite Micro and Nanostructures

Up-conversion is a process that can be used for infrared laser visualization. Lead halide perovskite has a fine opportunity to be employed for up-conversion. Halide perovskite has not only good photovoltaic and optoelectronic properties but also good photonic properties. Simple chemical fabrication methods and unique properties make perovskites cheap and attractive materials for different applications. In this article, we show different perovskite structures that possess up-conversion of near-infrared laser emission to visible green light.
