A comparative analysis of the thermal shift of Sm3+ ion zero-phonon lines in YAG and sesquioxide (Y2O3 and Sc2O3) ceramics is presented. The Sm3+ lines in YAG show small red shifts, whereas in sesquioxides large blue shifts in absorption (up to ~9 cm−1 Y2O3 or ~6 cm−1 Sc2O3), and blue or red shifts in emission are observed for the C2 centers, while the C3i magnetic-dipole allowed lines exhibit small red shift. The data are analyzed in terms of competition between the dynamic (due to electron-phonon interaction) and the static shifts produced especially by the thermal local structural changes.
