Abstract EN
This study deals with the effect of gamma rays and heat treatment on the absorption coefficient and energy gap of the glass and the times of irradiation (10, 20, 30, 40, 50, 70, 80)hrs treated thermally at temperatures (20, 50,100,150,200,250,300,350)oC for period time 15 min.
We found that the absorption coefficient increases with increasing the gamma rays and decreases with the temperature increases.
It was found that the values of the energy gap of the glass decreased with the increase of irradiation time at the range 40-50 hrs, and then increases when the irradiation time increasing, but it has been found that the thermal treatment will increases the values of the energy gap of the glass.
These increases and decreases in the values of the energy gap are may be related to formation of F-center or coloration center as a result of exposure to the radiation, while heating repairing the glass damage.
