ABSTRACT:
The invention relates to an ultraviolet to green light region silicate phosphor capable of being excited by radiation light source and its manufacturing method, particularly to white and multicolor systems light-emitting device. The material has luminous color in the range from blue to red color system. The essential composition of the phosphor is aMO.bM′O.SiO2.cR:xEu.yLn.zLv.δLm, wherein M is an element or a combination of elements selected from the group consisting of Sr, Ca, Ba and Zn; M′ is an element or a combination of elements selected from the group consisting of Mg, Cd and Be; R is one or two of B2O3and P2O5; Ln is an element or a combination of elements selected from the group consisting of Nd, Dy, Ho, Tm, La, Ce, Er, Pr, Bi, Sm, Sn, Y, Lu, Ga, Sb, Tb, Mn and Pb; Lv is an element or a combination of elements selected from the group consisting of Cl, F, Br, I and S; Lm is an element or a combination of elements selected from the group consisting of Li, Na and K.
