Abstract

Luminescent metal halides, as a type of luminescent semiconductor material, offer advantages that fulfill the requirements of emerging light source devices, such as high luminescence efficiency, good thermal stability, and tunable colorful emission. Blue light being one of the three primary colors plays a crucial role in the field of lighting and colorful displays. However, the progress in device performance of blue-light materials lags behind that of green and red-light materials. Currently, there have been numerous reports on metal halide perovskite blue-light materials, but a comprehensive review on the development and performance control of blue-light metal halides is yet to be found. This paper provides a comprehensive summary of the design strategies and luminescence mechanisms of blue-light perovskites with various luminescence centers, as well as their application progress in the fields of light-emitting diodes (LEDs), X-ray scintillators, information anti-counterfeiting and encryption. It also explores possible directions for subsequent performance improvement. This work aims to offer valuable insights and recommendations for the future development of blue-light metal halides, with significant implications for the fabrication of novel blue light devices and advancements in detection technology.
