Temperature dependence of the luminescence intensity in optical fibers of oxyfluoride glass with CdS and CdS x Se1 − x quantum dots

Abstract

The temperature dependences of the integral luminescence intensity in optical fibers of oxyfluoride glass with CdS and CdS x Se1 − x quantum dots have been studied in a temperature range of 25–250°C. It is established that heating in this range leads to luminescence quenching in accordance with a nearly linear law. This effect can be used for the creation of fiber-optic temperature sensors.
