The study is devoted to the possibility of using and Pr3+:LiYF4 microparticles and nanoparticles as luminescent thermometers in the temperature range of 80-320 K. The ratio of luminescence peaks corresponding to the transitions from the 3P0 state to two Stark sublevels of the 3H5 state of Pr3+ ions is considered as a temperature-dependent parameter. This system demonstrates an absolute temperature sensitivity of 0.0009 K-1 at a temperature of 185 K.
