Fluorescence features of Sm3+ ions in Na2SO4-MO-P2O5 glass system-Influence of modifier oxide

► Na2SO4-P2O5: Sm3+ glasses mixed with MgO, CaO and BaO have been synthesized ► Optical absorption and photoluminescence spectra have been investigated.► The values of A and β have been found to be the highest for 4G5/2→6H7/2 transition ► The quantum efficiency (η) is found to be the highest for BaO mixed glasses ► Relationship between structural modifications and η has been discussed at length.
