Abstract
The fluorescence properties of a thermographic phosphor in the form of single crystals of LuPO4: Dy(1%),Eu(2%) have been studied as a functi on of temperature by the use of a high-temperature oven integrated int o 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 diffe rential method of remote thermometry for high-temperature applications and for temperature measurements on moving components.
