The MgO-Ga 2 O 3 -SiO 2 (MGS) glass and glass-ceramic (GC) containing MgGa 2 O 4 nanocrystals and Dy 3 þ ions were prepared by a simple sol-gel method. MgGa 2 O 4 nanocrystals in MgO-Ga 2 O 3 -SiO 2 GC formed when the heating temperature reached 800 1C. The energy transfer from MgGa 2 O 4 nanocrysta
## Abstract Transparent glass‐ceramics with composition of 95SiO~2~–5LaF~3~ doped with 0.1 mol% of Ho^3+^ or co‐doped with 0.1 mol% of Ho^3+^ and 0.3 mol% of Yb^3+^ were synthesized by thermal treatment of precursor sol–gel glasses. Segregation of LaF~3~ nanocrystals in the matrix was confirmed fro
