Abstract

See full text

A zinc aluminate fluorescent material is provided having a formula: Zn1-xAl2O4:Mnx@Al2O3@My; wherein M is at least one metal nanoparticles selected from the group consisting of Ag, Au, Pt, Pd, and Cu; 0−2; @ represents coating, in the zinc aluminate fluorescent material, M serves as a core, Al2O3 serves as an intermediate layer shell, and Zn1-xAl2O4:Mnx serves as an outer layer shell. In the zinc aluminate 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 zinc aluminate fluorescent material exhibits a higher luminous intensity. A method of preparing the zinc aluminate fluorescent material is also provided.
