Abstract
The phase analysis, luminous intensity, and luminescence lifetime of different doping concentrations of Tb3+ (1 mol % - 11 mol %), Yb3+ (9 mol % - 54 mol %), Er3+ (0.1 mol % - 1.1 mol %) ions and different introduction concentrations of Y3+ (1 mol % - 6 mol %) and Lu3+ (0.5 mol % - 3 mol %) of Gd2O2S series phosphors were studied systematically. In addition, the energy transfer model of Tb3+-Yb3+-Er3+ was established by analyzing the changes of luminous intensity and luminescence lifetime of novel (Gd, Y, Lu)2O2S phosphors co-doped Tb3+, Yb3+ and Er3+ which were prepared by the coprecipitation-high temperature solid-state reaction method., The luminescence intensity ratio equations of the sample excited by 980 nm was obtained at 313-553 K. And the absolute sensitivities were 0.0033 (313 K). This work is of reference value to the study of the mechanism of up-conversion system.
