Recipe Details

SiO2 + CaCO3 + Na2CO3 were mixed with 1% of terbium oxide and 1.85% of europium oxide. Approximately 25 g batches were mixed and melted in platinum crucibles in an electric furnace at 1500 °C for 3 h in air. The melted glasses were quenched at room temperature and further annealed at ca. 550 °C for 1 h. The glass samples were cut and carefully polished.
