| 发明名称 | Stannate fluorescent material and method for preparing same | ||
| 摘要 | The present invention provides a stannate fluorescent material having a formula: A2-xSnO4:Eux@SnO2@My; wherein A is selected from the group consisting of Ca, Sr, and Ba; M is at least one metal nanoparticles selected from the group consisting of Ag, Au, Pt, Pd, and Cu; 0<x≦0.05; y is a mole ratio of M to Sn, and 0<y≦1×10−2; @ represents coating, in the stannate fluorescent material, M serves as a core, SnO2 serves as an intermediate layer shell, and A2-xSnO4:Eux serves as an outer layer shell. In the stannate fluorescent material, a core-shell structure is formed by coating at least one metal nanoparticles selected from the group consisting of Ag, Au, Pt, Pd, and Cu, since metal nanoparticles can improve the internal quantum efficiency of the fluorescent material, the stannate fluorescent material exhibits a higher luminous intensity. | ||
