Materiais vítreos com propriedades similares às do cristal germanato de bismuto de composição Bi4Ge3O12, material cintilador que possui estrutura do tipo eulitita, são de interesse devido as suas propriedades luminescentes, que os tornam promissores para aplicação como dispositivos ópticos. Vidros do sistema GeO2-Bi2O3 (BGO) também tem sido tema de inúmeras pesquisas por combinarem um típico formador vítreo (GeO2) a um formador condicional composto intermediário (Bi2O3), o que os proporciona características estruturais únicas, resultantes da mudança de coordenação dos átomos de germânio (fenômeno de anomalia do germânio) e também dos átomos de bismuto. Neste trabalho, estudou-se a influência da adição de CeO2, comumente conhecido como age...
