Influence of manganese ions on spectroscopic and dielectric properties of LiF-SrO-B2O3 glasses

► Spectroscopic and dielectric properties of MnO doped LiFSrB2O4 glasses were studied. ► Mn2+ and Mn3+ (VI) ions are increased with an increase of dopant in the glass network. ► Hyperfine splitting is found in low concentration of dopant. ► σac and dipole-dipole interactions are increased at higher concentration of dopant.
