Abstract

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 λ_exci = 402 nm (⁶H_5/2 →⁴F_7/2) and Dy³⁺:MgLaLiSi₂O₇ phosphors with λ_exci = 385 nm (⁶H_15/2 →⁴I_13/2) have been analyzed. Emission mechanisms of these phosphors have also been explained.
