More Information
Summary:A red light fluorescent material adapted for being excited by a first light to emit a red light is provided. The red light fluorescent material has the chemical formula (1) presented below, A2Eu(MO4)(PO4)  (1), in which A represents Li, Na, K, Rb, Cs, or Ag, and M represents Mo, W, or a combination thereof (MoxW(1−x)). The red light fluorescent material can provide a red light with high luminance and good color purity. Moreover, since the composition of the red light fluorescent material includes oxides, the red light fluorescent material has high chemical stability and long lifetime.
