HIGH EFFICIENCY ALKALINE EARTH METAL THIOGALLATE-BASED PHOSPHORS
Document Type and Number:
WIPO Patent Application WO2005026285
Kind Code:
A3
Abstract:
Provided, among other things, is a strontium calcium thiogallate phosphor doped with divalent europium, and having the following formula: Sr1-xCaxGa2S4:yEu<2+>.zGa2S3, where x is 0.0001 to 1, y is a value defining sufficient Eu<2+> to provide luminescent emission, and z is 0.0001 to 0.2 based on the mole amount of Sr1-xCaxGa2S4:yEu<2+>.
