Abstract

Green upconversion fluorescence of Er,Yb:YVO₄ and Er,Yb:YGdVO₄ are studied in the spectral range of 520-560 nm in the temperature range from room temperature to 150°C under 967 nm pumping. It is shown that the temperature measurement sensitivity of fluorescence intensity ratio sensors on the base of these crystals is about 0.008 K^-1 and is comparable with the corresponding values for Er-doped silica fiber.
