Strontium thiogallate (SrGa2S4) thin films have been prepared by rf reactive magnetron sputtering. This sulfur matrix permits the acceleration of charge carriers to optical energies under high electric field and provides green electroluminescence when doped with europium. The color coordinates are better than those achieved by other known green thin film electroluminescent phosphors. Strontium thiogallates as other ternary IIA-III2-(S,Se)4 compounds doped with Eu2+ or Ce3+ are good candidates for thin film electroluminescence phosphors of full color displays.
