Abstract

An optical temperature sensor based on the upconversion luminescence of Tm ³⁺ has been developed. Under a 980 nm diode laser excitation, the fluorescence intensity ratio (FIR) between 700 (Tm ³⁺: ³F ₂, ₃ → ³H ₆) and 800 nm (Tm ³⁺: ³H ₄ → ³H ₆) upconversion emissions from Tm ³⁺/Yb ³⁺ codoped oxyfluoride glass ceramic was studied as a function of temperature in the range of 293-703 K. The ³F ₂, ₃ and ³H ₄ states of Tm ³⁺ are verified to be thermally coupled levels. By using FIR technique, the sensitivity for detecting temperature variations achieved here is better than previous reported rare earth ions fluorescence based temperature sensors. With the advantages of intense upconversion luminescence and absolutely separated 700 and 800 nm emission bands, the Tm ³⁺/Yb ³⁺ codoped oxyfluoride glass ceramic is a very promising candidate for accurate optical temperature sensors with much higher sensitivity and resolution.
