Transparent glass-ceramics containing γ-Ga2O3:Co2+ nanocrystals are synthesized in the lithium gallium silicate system. The observed red-shift of the absorption band related to the 4A2g(4F)→4T1g(4F) transition of Co2+ ions in tetrahedral sites and absorption saturation properties indicate that the g...
