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 polymer substrate. Long afterglow phosphors, starch and ruby composites are used as phosphor of sensor array. Photoluminescence (PL) from phosphor composites on matrix sensor are evaluated using a fiber spectrometer. Two dimensional observation of PL from matrix sensor is also observed using CCD camera and UV illumination. Images processing technique is found to be effective for two dimensional evaluation of PL from the sensor array.
