| Summary: | Perovskite, particularly halide perovskite has drawn increasing attention in recent years because of its remarkable photoelectric properties. However, due to its susceptibility to environmental factors, its research and application have been hampered. Recently, perovskite nanocrystals (PNCs) have been precipitated inside glass by using thermal treatment or femtosecond laser irradiation, which results in unprecedented stability because they are protected by glass matrix. This article reviews the fundamental structure and properties of PNCs, the benefits of perovskite nanocrystals-glass composite structure, and the current state of research into the use of a femtosecond laser to induce PNCs in glass. We also discuss the recent progress in the use of perovskite nanocrystals-glass composite structure for stereo-holographic computing, micro-LEDs and optical storage.
