Improved One- and Multiple-Photon Excited Photoluminescence from Cd-Doped CsPbBr Perovskite NCs.

Metal halide perovskite nanocrystals (NCs) attract much attention for light-emitting applications due to their exceptional optical properties. More recently, perovskite NCs have begun to be considered a promising material for nonlinear optical applications. Numerous strategies have recently been developed to improve the properties of metal halide perovskite NCs.
