## 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
