In order to overcome the shortcomings in obtaining white light emission due to the anion exchange reaction from different halide perovskite quantum dots and unstable red light emission halide perovskite quantum dots， a method was used to prepare rare earth ions Tb³⁺/Eu³⁺ co-doping into perovskite quantum dots in ambient air. By adjusting the doping ratio of Tb³⁺/Eu³⁺ rare earth ions， the energy transfer from the host lattice of perovskite quantum dots to Tb³⁺/Eu³⁺ was accordingly manipulated to obtain single-component and white light emission perovskite quantum dots of （Tb， Eu）∶CsPbCl₃ and （Tb，Eu）∶CsPb（Cl/Br）₃. Meanwhile， we delicately investigated the morphology， structure， luminescence performance， energy transfer mechanism and stability of quantum dots. The results show that under 365 nm laser excitation， white light emission with 1 931 Commission Internationale de l’Eclairage color coordinates was achieved in perovskite quantum dots （Tb， Eu）：CsPbCl₃ with different contents of Tb³⁺/Eu³⁺ ions. When the feed ratio PbCl₂∶TbCl₃∶EuCl₃ is 1∶1.5∶1， the quantum yield is 3.59%， which is 6 times higher than the quantum yield （0.57%） of pure CsPbCl₃ quantum dots. Further research found that the （Tb， Eu）∶CsPbCl₃ quantum dots were stored in the air for 2 months， the quantum yield was almost unchanged （3.63%）， maintaining good stability. Moreover， the luminescence characteristics of the co-doped perovskite quantum dots with Tb³⁺ and Eu³⁺ synthesized with different solvents （n-octane， 1-octadecene） were compared. Tb³⁺/Eu³⁺ co-doped perovskite quantum dots （Tb， Eu）： CsPbCl₃ ware used to achieve single-component white light emission with good stability and has certain application prospects.
