Design of a high temperature sensing system using luminescence lifetime measurement.

Temperature sensing system has been designed and fluorescence lifetime measurements have been performed to estimate the temperature. (4)S(3/2) lifetime of LaF(3):Er(3+) and (5)S(2) lifetime of LaF(3):Ho(3+) have been measured as a function of temperature. Lifetime versus temperature calibration plots have been made up to 1000 degrees C.
