Abstract:  When -irradiated microcrystals of potassium halides are dissolved in the luminol solution, the lyoluminescence (LL) intensity initially increases linearly with time, attains an optimum value and then decreases and finally disappears. The LL intensity was detected by PMT whose output was connected to X-Y recorder. Temperature dependence of LL intensity shows that initially the peak of LL intensity (Im) increases with temperature, attains a peak value, and then decreases with further increase in temperature. Also, the total intensity IT initially increases, attains an optimum value and then it decreases with further increase in temperature. The decay time decreases with increasing temperature of the solvent, from where the value of activation energy Ea can be calculated. A plausible explanation for the experimental results is given.
