Abstract

Two-dimensional sensor array composed of various phosphors has been evaluated for fluorescence thermometer application. In a matrix sensor, 3times3 composite phosphors are separately located on 10times10 mm² square substrate. Two dimensional observation of photoluminescence (PL) from array sensor is curried out using CCD camera under UV illumination. Brightness of phosphors in the PL image varies linearly with temperature. Images processing technique (line scanning of intensity) is found to be effective for evaluation of PL from the sensor array.
