Paper Abstract

Fluorescence thermometer based on the temperature dependence of phase angle of fluorescence pulse was developed using long afterglow SrAl2O4:Eu,Dy and SrAl2O4:Eu,Nd phophors as the sensor materials. Phase angle sensitively varies with temperature. The phase angle measurement technique is potentially useful for the temperature sensing using long afterglow phosphors with extremely high sensitivity.
