Abstract

We study the luminescence properties of inorganic glasses doped with molecular clusters containing copper; such glass may be used as a sensor element in fiber-optic temperature sensors. We present luminescence spectra for potassium-aluminum-borate, sodium-aluminum-borosilicate, and alkali-aluminum-silicate glasses on the 293–623 K temperature interval. We demonstrate that the peak of the luminescence band undergoes a reversible shift within this temperature range (95 nm for borate glass, 90 nm for borosilicate glass, and less than 5 nm for silicate glass).
