摘要

The process of preparing Er~(3+)-doped barium borosilicate glass samples with different dopant concentrations using a high-temperature sintering technique is discussed. Under a 978-nm semiconductor laser excitation, the energy transfer from H_(11/2) ~2to l_(15/2)~4 and S_(3/2)~4 to l_(15/2)~4 caused by the transitions of Er~(3+) ions yields a 534- and a 549-nm green fluorescence. The relationship between the absolute temperature T and the fluorescence intensity ratio R of these two up-conversion photo-luminescence spectra is discussed and fitted to trie exponential function R= 1.782exp{-328/T) in the temperature range of 298 to 698 K. The sensitivity of the samples descends monotonously from 0.00219 to 0.00075 K~(-1) with the temperature increase from 298 to 698 K. The data are of undoubted repeatability, and the proposed doped glass is suitable for sensitive, high-temperature measurement.
