Abstract:

Halide perovskite-type ABX3 nanocrystals mainly including the optical properties and applications of all-inorganic ABX3 nanocrystals were reviewed. First of all, the two preparation methods of atmospheric pressure, solvent heating and ion-exchange process for all-inorganic nanocrystals are reported; then, the optical properties of their absorption and photoluminescence are elaborated in detail; finally, their applications in light emitting diode(LED) and solar cell are emphasically elucidated, and also involving in the fields of laser, photodetector and photocatalysis. In the recent future, the halide perovskite nanocrystals will also definitely exhibit other potential applications owing to the excellent optical and electrical properties.

Key words: Perovskite-phase, Halide, Nanocrystals, Optical property, Photoluminescence
