Highly Efficient and Environmentally Stable Flexible Color Converters Based on Confined CH3NH3PbBr3 Nanocrystals

In this work, we demonstrate a synthetic route to attain methylammonium lead bromide (CHNHPbBr) perovskite nanocrystals (nc-MAPbBr, 1.5 nm < size < 3 nm) and provide them with functionality as highly efficient flexible, transparent, environmentally stable, and adaptable color-converting films....
