Abstract
A core-shell structured silicate luminescent material and a preparation method thereof. The molecular formula of the luminescent material is: MLnSiO:xRE@SiO; where @ represents a coating, where M is one or two elements among Li, Na, and K, where Ln is one or two elements among Y, Sc, Lu and La, where the value of x is 0<x≦0.6; and where RE is one, two, or three elements among Tb, Gd, Sm, Eu, Dy, Ce and Tm. The compositions of the luminescent material are all chemicals of increased chemical stability, and, when subjected to electron beam bombardment for an extended period, provide a stable matrix and do not decompose easily.
