Abstract
A thermally luminescent temperature sensor with a rare earth emitter having a first selective electromagnetic light energy emission band and a second selective electromagnetic light energy emission band in which the rare earth emitter converts thermal energy to electromagnetic light energy within the first and second selective energy emission bands. The sensor also has a selective optical detector in optical communication with the rare earth emitter, wherein the selective optical detector independently detects each the first and second selective electromagnetic light energy emission bands. Lastly, the thermally luminescent temperature sensor determines the temperature based on the electromagnetic light energy measured within the first and second selective energy emission bands relative to each other. Optionally additional emission bands may be used in the evaluation of the temperature.
