|Abstract:||Optical absorption spectra of 3d transition metals have been measured in soda-lime phosphate glass before and after successive gamma irradiation. In general, the transition metals exhibit the lower oxidation state or octahedral coordination in phosphate glass. The experimental optical spectra are related to the respective specific transition of each transition metal ion. Transition metal-doped phosphate glasses reveal varying response to the effect of successive gamma irradiation. The intensity and growth behaviour of the radiation-induced bands are seen to depend on the type of the 3d transition metal. The response of the doped-phosphate glass to gamma rays irradiation is related to the formation of characteristic induced colour centers and the subsequent annihilation or approach of saturation.|
