A luminescent material of silicate is provided. The luminescent material has a formula of Ln2-x-ySiO5:Cex,Tby,Agz, wherein, Ln is one of Y, Gd, La and Lu, 0<x-0.05, 0.01y0.25, 0<z0.005. The method for preparing the luminescent material comprises the following steps: weighing the source compounds of Ln, Ce, Tb, Ag and silica aerogel; dissolving the silica aerogel in the alcoholic solution of the source compound of silver, stirring, drying and sintering to obtain silica aerogel containing Ag; after mixing the weighed source compounds of Ln, Ce, Tb and the silica aerogel containing Ag, sintering under reducing atmosphere to obtain the luminescent material of silicate. |
