Rare earth doped halosulphate specially fluoride based phosphor NaMg(SO4)Cl:Tb3+ have been synthesize by modified route of slow evaporation technique. Identification of crystal structure and particle morphology of synthesized material was done by using X-ray diffraction (XRD), scanning electron microscope (SEM) and Fourier transform infrared spectroscopy (FTIR) techniques. Iterations for photoluminescence properties of this material is of prime importance as absorption by the host material near the UV radiation edge have high excitation efficiency band at shorter wavelength than 230 nm wavelength which is characteristics of NaMg(SO4)Cl:Tb3+. This existence of excitation bands with high luminescence efficiency and deep green emission at 544 nm makes this material favorable as the phosphor for UV-LED fluorescent tubes.
