of the VPB/Zn glasses ranged from 0.688 to 0.710 eV, while from 0.560 to 0.647 eV for the indirect transition. The admission of the ZnO improves the MAC of the VPB/Zn glasses. Thus, one can conclude that the proposed glasses can be applied for optical devices as semiconductor glasses and considered as good materials for γ-rays shielding. |
