Provided, among other things, is a strontium calcium thiogallate phosphor doped with divalent europium, and having the following formula: <?in-line-formulae description="In-line Formulae" end="lead"?>Sr<SUB>1-x</SUB>Ca<SUB>x</SUB>Ga<SUB>2</SUB>S<SUB>4</SUB>:yEu<SUP>2+</SUP>.zGa<SUB>2</SUB>S<SUB>3</SUB>,<?in-line-formulae description="In-line Formulae" end="tail"?> where x is 0.0001 to 1, y is a value defining sufficient Eu<SUP>2+</SUP> to provide luminescent emission, and z is 0.0001 to 0.2 based on the mole amount of Sr<SUB>1-x</SUB>Ca<SUB>x</SUB>Ga<SUB>2</SUB>S<SUB>4</SUB>:yEu<SUP>2+</SUP>.
