green emitting phosphor has been studied as a luminous device for CRT (Cathode Ray Tube) or FED (Field Emission Display) and EL (Electroluminescence). This phosphor, also, is under noticed for LED (Lighting Emitting Diode) phosphor, which makes use of excitation characteristics of long wavelength region. The SrGa2S4:Eu 2 + phosphor was prepared generally conventional synthesis method using flux. However, this method needs high heat-treated temperature, long reaction time, complex process and harmful H2S or CS2 gas. In this works, therefore, we have synthesized SrGa2S4:Eu 2 + using SrS, Ga2S3, and EuS as starting materials, and the mixture gas of 5% H2/95% N2 was used to avoid the H2S or CS2. We investigated the luminescence characteristic of SrGa2S4:Eu
