Abstract
In this article, we present the investigations of temperature dependent luminescence for the Ag0.05Ga0.05Ge0.95S2-Er2S3 glass system. The possibility to use temperature dependences of the photoluminescence of synthesized glasses for thermo sensors is considered. It is shown that logarithm of ratio of the integrated photoluminescence intensities for 980 and 600Â nm (ln (I980/I660)) emission bands possess excellent linear dependence of temperature. At the same time, the nonlinear optical effects of two-photon absorption show substantial divergence from the sublinear dependences. These phenomena provide an opportunity to utilize Ag0.05Ga0.05Ge0.95S2-Er2S3 glasses for the fabrication of highly sensitive temperature sensor devices.
