Silicate luminescent material and preparation method thereof are provided. The structural formula of the silicate luminescent material is Zn2-y(Si1-xMx)O4:Mny, wherein M is metal element and its oxide is conductive, x is in a range of 0.001 to 0.15, and y is in a range of 0.001 to 0.05. For integrated with conductive metal oxide component, the silicate luminescent material could take advantage of its conductive properties, and the silicate luminescent material could improve the luminescence properties under cathode ray significantly comparing with that of the luminescent material has not been integrated with conductive component. Accordingly, the luminescence efficiency of the above silicate luminescent material is increased.
