%X In this paper, we investigated the effect of luminescence properties of various concentrations of magnesium-dopedZnS:Mn phosphor excited by plasma luminescence device. The PL intensity was evaluated in the range of 300~500nm excitation wavelengths. We found the highest PL intensity of the phosphors excited by 365 nm and 450 nm wasobserved at Mg concentrations of 1.4 wt% and 0.8 wt%, respectively. In addition, an emission peak was distinguishedat 580 nm wavelength. With increasing Mg dopant level, enhanced PL intensity was observed, which is possiblyapplicable to color converting materials by blue emission for white light sources. Finally, we evaluated the luminanceproperties of color converting ZnS:Mn,Mg phosphors with plasma blue light source. the white luminance of plasmalight source with CIE(0.36,0.26) was established by color converting phosphors of ZnS:Mn with 0.8 wt% Mg.
