Lead tungstate PbWO 4 nanocrystals in transparent lead borate glass‐ceramics containing Er 3+ ions were fabricated. Luminescence spectra at about 1530 nm due to main 4 I 13/2 – 4 I 15/2 laser transition of Er 3+ ions were examined for glass samples before and after heat treatment. Near‐infrared luminescence of Er 3+ ions in glass‐ceramics is enhanced and long‐lived in comparison to precursor glasses. It suggests that the Er 3+ ions are partially incorporated into PbWO 4 crystalline phase.
