Optical Properties of CsPbX₃ Quantum Dots Embedded Glass-Ceramics

CsPbX₃ (X=Cl, Br, I) perovskite quantum dots embedded glass-ceramics (GCs) are a composite material with the steady physical and chemical properties of glass matrix phase and the superior optical performance of CsPbX₃ quantum dot phase. These materials are used in optical data storage, random laser, X-ray image, lighting and display, solar cells, photocatalysis, etc.. Recent advances on the preparation and the corresponding performance/application were introduced, i.e., the use of fs laser to form CsPbX₃ in selected zone to serve as optical data storage, thereby showing the regular pattern of these materials’ composition-structure-performance relationship. Nevertheless, these are some challenges of investigating for these materials, i.e., the in-situ formation of CsPbX₃ in glass matrix is entirely unclear. And the studies on CsPbX₃ precursors’ occurrence state, neighbor structure and morphological distribution could further help to understand the formation mechanism of CsPbX₃ in glass, providing a guide to obtain the better CsPbX₃ perovskite quantum dots embedded GCs.
