Effect of temperature on the ML of Au doped (Zn,Cd)S mixed phosphors

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 relation I = 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.
