Research Abstract |
Red emission was observed from Mn(or Ce, Mn)-doped glaserite-type alkaline-earth silicates M_3MgSi_2O_8 (M: Ba, Sr, Ca) under ultraviolet irradiation. The red emission became intense with an increase in Ba-amount for M. This trend was caused by structural deformation due to barium occupation for layer pockets. Glass-ceramics containing M_3MgSi_2O_8 crystalline phase were successfully prepared by adding aluminum.
