【Abstract】 The preparation process of Er3+-doped silicate glass was presented.In the temperature range of 298~698 K,the relationship between the Absolute temperature T and the fluorescence intensity ratio R of two green up-conversion photoluminescence spectra emitting from the trivalence erbium ions doped in the silicate substrate was discussed and fitted to the analytic function of R=1.782×exp(-328/T).The sensitivity of the sample descends monotonously from 0.002 19 K-1 to 0.000 75 K-1 when the temperature rises from 298 K to 698 K.The results show that the Er3+-doped silicate glass could be used as a high sensitivity sensor and play a major role in temperature measurement below 698 K.更多还原
