1. A strontium calcium thiogallate phosphor doped with divalent europium, and having the following formula:


  • Sr1-xCaxGa2S4;

    yEu2+.zGa2S3,where x is a value such that both Sr and Ca are present and is greater than or equal to 0.0001, y is a value defining sufficient Eu2+ to provide luminescent emission, and z is greater than 0.07 up to 0.2 based on the mole amount of Sr1-xCaxGa2S4.
