Abstract In this paper the effect of temperature on the mechanoluminescence of Au doped phosphors of(Zn,Cd)S is described.It is found that the ML disappears beyond a particular temperature.The temperature dependence of ML intensity follows the relationiI=IT0(1-T/TC)n, where IT0 is a constant, n is the slop of log IT versus log(1- T/TC)plot which lies between 0.9 and 1.10, TC is the temperature at which ML disappear.It is found that the ML intensity in(Zn,Cd)S:Au disappear at 600 K.
