Aluminate fluorescent materials and preparation methods thereof are provided. The fluorescent materials include a core and a shell coating the core. The core is metal nano particle, the shell is fluorescent powder represented by the following chemical formula: (Ce 1-x Tb x )MgAl 11 O 19 . wherein 0<x‰¤0.7. The aluminate fluorescent materials with high luminous efficiency are not only uniform in the aspect of particle size distribution, but also are stable in the aspect of structure. The preparation methods which have simple technique and low pollution are appropriate to be used in industry. |
