Abstract
There are promising crystals for fluorescent and LISICON materials in Li2O-ZnO-GeO2 system, e.g., Li2ZnGe3O8 and Li2ZnGeO4. On the other hand, glass and glass-ceramics in this system have not been studied in detail up to now. Therefore, we investigated crystallization behavior of several glasses in Li2O-ZnO-GeO2 system, and photoluminescent (PL) properties were examined in the glass-ceramics in this system. A glass-ceramics indicated clear blue PL at room temperature.
