Have you ever wondered why blue light-emitting perovskite materials aren't as efficient as they could be? The problem lies in intrinsic defects that trap charge carriers. Scientists have found a clever solution: wrap CsPb(Cl/Br)3 nanocrystals in silica. This combination, known as CsPb(Cl/Br)3 NCs@SiO2, shows higher photoluminescence intensity and lifetime compared to...
