N2 - An extrinsic optical fibre temperature sensor has been investigated and results are presented. A coating consists of a combination of two inorganic phosphors. Thermal quenching dominates the luminescent characteristics of one phosphor at temperatures in the range of interest while the other more stable phosphor is used as a reference. Ratios of their peak emission intensities are calculated and analysed. The phosphor mixture is coated onto a Pyrex beaker. Boiling water is poured into beaker and the ratio is calculated as the temperature of the water decreases from 80°C to 30°C. Results show an increasing ratio for decreasing temperature. This paper describes the testing of the coating and its application, as part of a temperature sensor, for monitoring surface temperatures in electromagnetically harsh industrial environments. Phosphors, fibre optic sensor, temperature, microwave, luminescent coating.
