Luminescence thermometry based on Y 2 O 2 S:Er,Yb nanophosphor

We present possibility analysis of using Y 2 O 2 S: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 Y 2 O 2 S:Er,Yb material with other thermophosphors, showing its usefulness for temperature measurements up to 620 K.
