Abstract
The invention belongs to the field of luminescent materials. Disclosed are silicate luminescent materials doped with metal nano particles and preparation methods there for. The silicate luminescent materials doped with metal nano particles are represented by the chemical formula:MLnSiO:xRE,yA; wherein M is one or two elements selected from Li, Na and K; Ln is one or two elements selected from Y, Sc, La and Lu; A is a metal nano particle selected from Ag, Au, Pt, Pd and Cu; RE is one or two ions selected from Eu, Gd, Tb, Tm, Sm, Ce and Dy; 0<x≦0.1; 0<y≦0.005. When silicate luminescent materials doped with metal nano particles of the invention are excitated by electron beam, they have higher luminescent efficiency. The luminescent materials are good to be used in field emission light source devices.
