Glass materials of the system (100-x)GeO2-xBi2O3, that have similar properties to the eulytite crystal (Bi4Ge3O12) are of great interest for their potential applications as scintillator detectors. Therefore, in order to extent the applicability of these glasses, their doping with different cations and structural characterization represents a hot research topic. Moreover, glasses having adequate scintillator properties consists an advanced for the development of scintillator detectors due to their sizes, mechanical strengths, easy preparation, and lower manufacturing costs comparing to single crystals. Glasses in the composition of 80GeO2-20Bi2O3 in mol% and doped with 0.2 mol% of CeO2 were prepared by the melting/quenching technique at 1100°C, in Pt crucibles. We have been reporting the role of silver in a novel process to obtain translucent crystallized glasses by inducing the formation of the Bi4Ge3O12 scintillator phase on the surface of the samples at temperatures 30°C below their glass transition (Tg ~ 480 °C).
