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.
