The fluorescence intensity ratio technique for optical fiber-based point temperature sensing is reviewed, including the materials suitable for this technique. The temperature dependence of the fluorescence intensity ratio has been studied using thermally coupled energy levels in seven different rare earth ions doped into a variety of glasses and crystals. Sensor prototypes developed using Pr31:ZBLANP, Nd31-doped silica fiber and Yb31-doped silica fiber as the sensing material have been used to measure temperatures covering the range of approximately 250 to 600 °C with a resolution of the order of 1 °C.
