Abstract

Abstract: A transparent ferroelectric 0.75Pb(Mg1/3 Nb2/3 )O3 -0.25PbTiO3 :0.015Pr 3+ ceramic was synthesized and its temperature-sensing ability was investigated based on the fluorescence intensity ratio (FIR) method. The transparency was found to be of the order of 68% at 900 nm for a sample thickness of 0.7 mm, comparable to the theoretical value of ~71%, benefiting the photoluminescence of the Pr 3+ ions inside the ceramic. Instead of the traditional Boltzmann exponential style and varying sensitivity, a highly linear temperature response was obtained for the studied ceramic. Further, a constant FIR sensitivity of 0.70 %K -1 was achieved over the temperature range of -50–40 °C, making the ceramic suitable for thermometry at room temperature and below.
