<p>Halo-silicate luminescent materials and preparation methods thereof are provided. The said luminescent materials are represented by the following general formula: (Ba 1-y A y ) 2-x SiO 4 :Eu x ,D z @ M n , wherein A is selected from one or two of Sr, Ca, Mg or Zn, D is selected from one of F or Cl, M is selected from at least one of Ag, Au, Pt, Pd or Cu metal nano-particles; @ is coating; (Ba 1-y A y ) 2-x SiO 4 :Eu x ,D z is shell; 0.001<x‰¤0.15, 0<y‰¤0.5, 0‰¤z‰¤0.5, 0<n‰¤1×10 -2 . The said luminescent materials have excellent chemical stability and high luminous intensity. Furthermore, the luminescent materials have controlled spherical shape which is beneficial to the coating screen process and the improved displaying effect. The said preparation methods have simple technique, no pollution, manageable process conditions and low equipment requirement, and are beneficial to industry production.</p> |
