Effect of thermal neutron irradiation on Gd3+ ions doped in oxyfluoroborate glass: an infra-red study

Infrared spectra of oxyfluoroborate glasses of composition (70-x)H{sub 3}BO{sub 3}+20Li{sub 2}CO{sub 3}+xGd{sub 2}O{sub 3}, where x=0, 0.5, 1.0, 3.0 and 5.0 mol%, have been recorded to explore the role of Gd{sup 3+} ions in the structure of the glasses. We concluded that Gd{sup 3+} ion behaves as a glass modifier. The effect of thermal neutron irradiation on the structure of these glasses also has been explored and the changes compared with earlier results on {gamma}-irradiation.
