Abstract:
Thermoluminescence (TL) glow curves of X-irradiated KCl (Pure),KBr (Pure) and KCl-KBr mixed crystals have been studied in the different dose of X-irradiation with periods 40minutes,60 minutes& 120 minutes with temperature range 25-300 degrees C. A plot of the peak height against composition shows a minimum at KCl0.52: KBr 0.48. The glow curves were analyzed and the variation of activation energy with composition has also been studied. The variation of peak temperature and the relative intensity of the peaks with respect to the composition the addition of Br-ions to the KCl lattice has been found to be more effective in enhancing the Thermoluminescence (TL) of KCl-KBr solid solution.
