## Abstract Raman scattering, optical absorption and photoluminescence studies have been performed on Er^3+^‐doped Na~2~O–Nb~2~O~5~–GeO~2~ germanate‐based glasses. The main bands in the Raman spectra involve vibrational modes associated with the germanium oxide network. Judd–Ofelt intensity paramet
