Nb2O5 nano-powder doped with Er3+ and Yb3+ ion can emit strong up-conversion emissions under infrared (975 and 1550nm) excitation. The intensities of the up-conversion emissions is very sensitive to temperature. Based on luminescence intensity ration, the thermal sensitivity had been studied. Under 1550nm excitation, the relative sensitivity SR1 is higher at 300-460K range, whose maximal value is 9.13%/K.
