Characterization of high-temperature thermographic phosphors: spectral properties of LuPO(4):Dy(1%),Eu(2%).
The fluorescence properties of a thermographic phosphor in the form of single crystals of LuPO(4):Dy(1%),Eu(2%) have been studied as a function of temperature by the use of a high-temperature oven integrated into a spectrophotometer. The results reveal differing rates of decrease in the fluorescence intensity with increasing temperature for various emission lines of dysprosium and europium, thus suggesting a new differential method of remote thermometry for high-temperature applications and for temperature measurements on moving components.
