Abstract
We present possibility analysis of using Y2O2S:Er,Yb for temperature sensing. Material samples were obtained by solution combustion method. We have used pulsed laser diode excitation at 980 nm. Our analysis is based on time resolved luminescence spectra acquired by a streak camera. Intensity ratios of prominent luminescence peaks were used for determining the temperature sensing curves. We compare the synthesized Y2O2S:Er,Yb material with other thermophosphors, showing its usefulness for temperature measurements up to 620 K. [ABSTRACT FROM AUTHOR]
