Rare EarthDoped Lead Halide Perovskites: Synthesis, Properties and RadiationDetectors

In recent years, lead halide perovskites have shown excellent performance in photovoltaic devices and photodetectors due to its excellent semiconductor properties and have become a hot spot in materials science.Doping rare earth elements is a promising way to improve the performances of lead halide perovskites. In this paper, we review the latest research progress of rare earths doped lead halide perovskite materials in the preparation, structures, properties, as well as radiation detectors. The doped rare earths introduce new luminescent centers and energy levels for new luminescence properties, improving the crystallinity and semiconductor performances of perovskite crystals. Therefore, rare earth doping can further improve the performance of lead halide perovskite radiation detectors.
