Stuctural, optical and radiation shielding properties of zinc boro-tellurite alumina glasses

In this work, boro-telluride glasses with additional zinc, aluminum, and alkali–alkaline modifiers have been synthesized using the melt-quenching–annealing method. Six glasses were fabricated with composition of [(60 − x)B₂O₃–(10 + x)TeO₂–10ZnO–10Al₂O₃ 5Li₂O–5MgO] all in mol% and x varied from 0, 10...
