Title

Synthesis and characterization of Sm, Li activated MgB4O7 phosphors

Abstract

In the present study, Sm, Li -activated Magnesium borate (MgB4O7) phosphors were synthesized by the solid-state reaction method. The crystal structure was determined by X-ray diffraction (XRD), surface morphology by scanning electron microscopy (SEM), and the nature of bonding by Fourier-transform infrared (FTIR) spectroscopy. The X-ray diffraction pattern exhibited the crystal structure of the prepared phosphors along with JCPDS data 31-0787. The photoluminescence excitation spectra of MgB4O7: Sm, Li displays a most intense peak at 408 nm corresponding to 6H5/2 → 4K11/2 transition, and emission spectra show the two characteristic bands at 578 nm and 602 nm. The strongest emission peak was obtained at 602 nm due to the excitation of Sm3+ ions from 4G5/2 to 6H7/2 transition. Raman spectroscopy determined the vibrational and bonding behavior of prepared samples and no peak shifting was observed in the host matrix after 2 mol concentration.
