Abstract :
Photoluminescence (PL) imaging is curried out using Cr doped spinel sensors at various temperatures for 2-dimensional fluorescence thermometer application. PL images can be clearly observed using a CCD camera and UV, green and/or blue LED illuminations. Brightness of PL images from Cr doped spinel sensor decrease with temperature up to 250degC. PL imaging is suggested to be useful for 2-dimensional fluorescence thermometer applications.
