摘要：
Sr3LiSbO6: Eu3+ red phosphors were synthesized by high temperature state reaction. The influence of Eu3+ concentration on the luminous intensity was systematically studied, and the samples were analyzed by XRD, fluorescence spectroscopy(PL), fluorescence lifetime, thermal stability and color coordinates. The results show that the prepared phosphor Sr3LiSbO6: Eu3+ can be excited by ultraviolet light and exhibits a strong red light emission band at 612 nm. The concentration quenching effect of the sample was studied, and the best doping concentration of the sample was 0.04%, which was mainly caused by the dipole-dipole interaction. In addition, the thermal stability of the sample was also discussed. The luminous intensity at 423 K was 43.1% of that at room temperature. Finally, the fluorescence lifetime and CIE of the samples were tested. The above results indicate that the prepared phosphor Sr3LiSbO6: Eu3+ has great prospects in the synthesis of LEDs. © 2021, Science Press. All right reserved.
