具有多个发射峰的硅酸盐基发光材料，其制备方法和使用其的发光器件

Silicate base luminescent materials having multiple emission peaks, processes for preparing the same and light emitting devices using the same
Abstract:
A silicate luminescent material excitable by an excitation light source having emissions in UV to blue light region, a process for producing the same, and a white light emitting device. The luminescent material has an emission spectrum with at least two peaks in a range of from 370 to 760 nm, and has a general chemical composition formula of aAO.bA′O.cSiO2:xEu.yLn.zM.δN, wherein A is selected from the group consisting of Sr, Ca, Ba, and combinations thereof; A′ is selected from the group consisting of Mg, Zn, and combinations thereof; Ln is selected from the group consisting of Nd, Dy, Ho, Tm, La, Ce, Er, Pr, Bi, Sm, Sn, Y, Lu, Ga, Sb, Tb, Mn, Pb and combinations thereof; M is one or a combination of halogen ions; N is selected from the group consisting of Li+, Na+, K+, Ag+, and combinations thereof; and a, b, c, x, y, z, and δ are molar coefficients.
