Abstract
Disclosed is a metal nanoparticle-coating silicate luminescent material, which has a molecular formula of LiCaSiO:Tb@M; where @ represents a coating, M is at least one among Ag, Au, Pt, Pd, and Cu nanoparticles, wherex≦where y is the molar ratio between M and Si, and wherey≦. The composition of the silicate coated metal nanoparticle luminescent material is metal nanoparticles coated with LiCaSiO:Tb, 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.
