Abstract

See full text

The present invention provides a silicate luminescent material, wherein said silicate luminescent material has a general molecular formula of Li2Ca1-xSiO4:Tbx,My, Tb and M are doped in Li2Ca1-xSiO4, and Tb and M are doped particles; M is selected from at least one of Ag, Au, Pt, Pd, and Cu metal nanoparticles, x has a value range of 0−2. The silicate luminescent material doped with metal particles greatly increases luminescent efficiency of the silicate luminescent material in a same excitation condition without changing a wavelength of emitted light. The silicate luminescent material has good stability, overcomes the defect that sulfide and oxysulfide series luminescent materials are easy to decompose, and can replace the sulfide and oxysulfide series luminescent materials in field emission display. Also provided is a preparation method thereof.
