Abstract
Disclosed is a metal nanoparticle-coating silicate luminescent material, which has a molecular formula of Li2Ca1−xSiO4:Tbx@My; where @ represents a coating, M is at least one among Ag, Au, Pt, Pd, and Cu nanoparticles, where 0<x≦0.2, where y is the molar ratio between M and Si, and where 0<y≦1×10−2. The composition of the silicate coated metal nanoparticle luminescent material is metal nanoparticles coated with Li2Ca1−xSiO4:Tbx, all of which are substances having great chemical stability and having great stability when bombarded by large electron beams. Also provided in the present invention is a method for preparing the metal nanoparticle coating silicate luminescent material.
