The phosphor emitting the phosphorescence for more than 10 micro seconds by an excitation was measured at the high time resolution, while the phosphorescence life time is the function of the temperature. A phosphorescence dyes, PtT975 or PdT975, was bound with acrylic resin onto the white paper. The dye was excited by a LED-array with the wavelength of 405nm. Phosphor was detected by a PIN photo diode or a cooled CCD camera. The basic properties of phosphors, emission spectra and lifetime, were investigated at first. Then, the temperature measurement was conducted by using a hotplate and a Nichrome wire heater. As a result, it was clarified to be able to measure the temperature using these dyes.
