Abstract:

Lead based halide perovskite luminescent materials have attracted much attention due to their excellent properties such as flexible crystal structure, tunable bandgap, defect tolerance, and high fluorescence quantum yield. However, the toxicity of lead metal and the stability of perovskite have always been issues that hinder its commercial application and urgently need to be addressed. Therefore, exploring greener and more environmentally friendly non lead metal halide perovskite luminescent materials is becoming an increasing research topic. In recent years, non lead double perovskite structures, in which lead ions are replaced with monovalent and trivalent metal ions, have successfully achieved low toxicity and high stability, but their photoluminescence efficiencies are extremely low due to the indirect bandgap or parity-prohibited direct bandgap. To address this issue, scientists have explored ion doping strategies and successfully achieved a significant improvement in photoluminescence efficiency. In this article, the crystal structure and luminescent properties of non lead double perovskite materials are summarized. Second, the effects of doping with main group metals, rare earth metals, and transition metals on the luminescence performance and luminescent mechanism are summarized. Finally, the application of ion doping strategies and improving the performance of non lead perovskite luminescent materials are summarized and discussed.

Key words: Double perovskite quantum dots, Ion doping, Photoluminescence quantum yield, Self-trapped exciton luminescence
