| Abstract |
| UV-visible and infrared absorption spectra of 3d transition metals-doped sodium borate host have been measured before and after successive gamma-irradiation. Transition metals are known to exhibit characteristic absorption bands. Infrared absorption spectra of the prepared samples exhibit characteristic bands indicating the coexistence of 3- and 4-coordinated boron groups. Transition metals reveal varying response in the UV-visible spectra to the effect of successive gamma irradiation while minor effect is obvious in the infrared spectra. The traditional and induced spectral data are analyzed and interpreted on the basis of current views on the effect of ionizing irradiation on glass. |
