Emission analysis of Sm3+ and Dy3+:MgLaLiSi2O7 powder phosphors

This paper reports on the structural and emission properties of newly synthesized Sm3+ and Dy3+:MgLaLiSi2O7 powder phosphors based on the measurement of their XRD, SEM, FTIR and photoluminescence spectra. Emission spectra of the Sm3+:MgLaLiSi2O7 phosphors with λexci = 402 nm (6H5/2 → 4F7/2) and Dy3+:MgLaLiSi2O7 phosphors with λexci = 385 nm (6H15/2 → 4I13/2) have been analyzed. Emission mechanisms of these phosphors have also been explained.
