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.
