Stable, Low-Threshold Amplification Spontaneous Emission of Blue-Emitting CsPbCl2Br1 Perovskite Nanocrystals Glasses with Controlled Crystallization

The inherent instability severely limits the applications of cesium lead halide (CsPbX3) perovskite quantum dots (PQDs). Herein, introducing these CsPbX3 PQDs into all-inorganic amorphous solid mat...
