Three-wavelength exciting up-conversion luminescence and various optical temperature sensing of a novel Er3+, Yb3+, Ho3+ doped (Gd,Y,Lu)2O2S phosphor

Abstract

In this paper, a three-wavelength exciting and temperature-sensing Gd1.559Y0.03Lu0.02Er0.13Yb0.26Ho0.001O2S phosphor excited by 980 nm, 1064 nm and 1550 nm was prepared for the first time by a coprecipitation-high temperature solid-state reaction (HSR). Three different up-conversion changes were observed with an increase in temperature under 980 nm, 1064 nm and 1550 nm laser excitation. The fluorescence intensity ratio (FIR) equations of the sample excited by 980 nm, 1064 nm and 1550 nm were obtained at 313–553 K. The three kinds of absolute sensitivity were 0.0016 (479 K), 0.0096 (553 K) and 0.1528 (553 K). The up-conversion process excited by 980 nm, 1064 nm and 1550 nm laser radiation was analyzed and the causes of the three different changes are explained. The stability of the Gd1.559Y0.03Lu0.02Er0.13Yb0.26Ho0.001O2S phosphor as a temperature sensor was tested by a cyclic test. It is proved that the Gd1.559Y0.03Lu0.02Er0.13Yb0.26Ho0.001O2S phosphor is a novel and valuable up-conversion optical temperature sensor.
