A new orange-red luminescent powder phosphor of NaMgSO4F: Sm3+ has been developed by re-crystallization method to characterization them spectroscopically in order to identify the most suitable phosphor as solid state lightening devices. For this material X-ray diffraction, Fourier transform infrared spectroscopy (FTIR) characterization and SEM features have also been investigated to explore the structural details. Besides carrying out these essential measurements, we have also made an attempt to observe two intense emission band 4G5/2 6H7/2 (orange) and 4G5/2 6H9/2 (red) a strong reddish-orange emission band performance displayed by this phosphor under an excitation band 6H5/2 4F7/2(blue).
