Luminescent material, especially for LED application

An ultraviolet-blue excitable green luminescent material comprises a europium doped oxynitride host lattice. The europium doped host lattice is of formula MSi 2O 2N 2 (where M is at least one of an alkaline earth metal selected from calcium (Ca), strontium (Sr), barium (Ba)). The luminescent materia...

More Information
Summary:An ultraviolet-blue excitable green luminescent material comprises a europium doped oxynitride host lattice. The europium doped host lattice is of formula MSi 2O 2N 2 (where M is at least one of an alkaline earth metal selected from calcium (Ca), strontium (Sr), barium (Ba)). The luminescent material is excitable in the ultraviolet blue region of 380 - 470 nm. The proportion of europium is 0.1 - 30%.
