Abstract

The up-conversion optical emission temperature sensing of Er3+-doped (Ba0.97Ca0.03)(Sn0.06Ti0.94)O3 piezoelectric ceramic prepared via a conventional solid-state reaction method has been investigated in a range of 83-503K. There is a good linear relationship between the logarithm of the fluorescence intensity ratio of the green up-conversion emissions at 525nm and 550nm peaks (Ln(I525/I550)) and the inverse of temperature (1/T). The maximum temperature sensitivity was found to be approximately 0.0051k-1, suggesting that Er3+-doped (Ba0.97Ca0.03)(Sn0.06Ti0.94)O3 ceramic possesses potential application in optical non-contact temperature sensing.
