发明名称 ALUMINATE LUMINESCENT MATERIAL AND PREPARATION METHOD THEREFOR
摘要 An aluminate luminescent material with a general molecular formula of Y3-xAl5O12:Lnx,My is provided, Ln is selected from at least one of Ce and Tb; M is selected from at least one of Ag, Au, Pt, Pd, and Cu, x is in a range of 0<x≦0.05, y is a molar ratio of M to Al and y is in a range of 0<y≦1×10−2. The aluminate luminescent material is formed by codoping Ln and M in a Y3-xAl5O12 substrate, of which M can improve internal quantum efficiency and luminescent intensity of the luminescent material. In addition, Y3-xAl5O12 has high stability, which can prevent a phenomenon where luminescent efficiency of the luminescent material is reduced because a traditional sulfide and sulfur oxide decompose during use and sediment generated in decomposition covers a surface of the luminescent material. Also provided is a preparation method thereof.
