Under 980nm excitation, optical temperature sensing properties based on the upconversion emissions of Tm3+ in LiNbO3 polycrystal and single crystal are studied in the temperature range of 323–773K. It is observed the 3F2,3 and 3H4 levels of Tm3+ are thermally coupled levels in both LiNbO3 polycrystal and single crystal, suggesting that the Tm3+-doped LiNbO3 crystals possess potential application in...
