This paper presents the results of studying the temperature dependence of up-conversion "green" photoluminescence (PL) in a congruent LiNbO3: Er3+ crystal excited by a laser diode operating at a wavelength of 808 nm. The study covers the temperature range from 77 to 413 K. Our results show that the temperature-dependent intensity ratio of green PL emitted by thermally bound states of the erbium ion (2H11/2 and 4S3/2) can be used as a thermometric sensor. It is noteworthy that LiNbO3: Er3+ exhibits absolute temperature sensitivity (0.0044-0.0055 K-1), which is one of the highest for materials activated by rare-earth ions, in the temperature range of 20-50oC, which is relevant for physiological measurements. This observation suggests that materials based on LiNbO3: Er3+ have great prospects for optical (contactless) temperature measurements in biological media. Keywords: Photoluminescence, Erbium, Up-conversion, Thermometry.
