Yellow Phosphor Having Oxyapatite Structure, Preparation Method and White Light-Emitting Diode Thereof

Abstract

A yellow phosphor having oxyapatite structure, preparation method and white light-emitting diode thereof are disclosed. The yellow phosphor has a chemical formula of (A1−xEux)8−yB2+y(PO4)6−y(SiO4)y(O1−zSz)2, wherein A and Eu are divalent metal ions, B is a trivalent metal ion, 0<x≦0.6, 0≦y≦6, and 0≦z≦1. A can be an alkaline earth metal, Mn or Zn. B can be a group 13 metal, a rare earth meal or Bi.
