摘要：

An Er3+-doped calcium aluminate glass has been studied in order to establish its suitability as optical temperature sensor based on the fluorescence intensity ratio technique. Temperature-induced changes in the relative intensities of the green emissions associated with the transitions from the H-2(11/2) and S-4(3/2) thermalised levels to the I-4(15/2) ground state under laser excitation at 488 nm has been measured in the range of temperatures from 150 to 762 K. The sensitivity obtained due to temperature changes shows a maximum of 159 x 10(-4) K-1 at 645 K, one of the highest sensitivity values found in Er3+ -doped host matrices. Compared to other studies, a different approach has been followed to estimate the calibration the temperature sensor using a low-cost prototype. (C) 2016 Elsevier B.V. All rights reserved.
