  • Patent number: 7758775
    Abstract: This invention relates to a green phosphor and a process for producing the same, wherein the phosphor is represented by a chemical formula: M(Tb1-xLax)4Si3O13, where M includes at least one of Ca and Sr, and 0<x<1, and is obtained by mixing at proper ratios and calcining at a high temperature in an oxygen-containing atmosphere. When the produced phosphor is excited by a near ultra-violet light of 378 nm, a green light having its main peak at 541 nm is emitted, and the x and y values of its CIE coordinate are in respective ranges of (0.34-0.37) and (0.52-0.55). The method for producing the phosphor includes steps of weighing and mixing the ingredient powder, and calcining in the oxygen-containing atmosphere at high temperature to form the phospher.
