Claim:
1. A method for preparing a germanate luminescent material, comprising: preparing a colloid containing M, wherein M is at least one of Ag, Au, Pt, Pd and Cu nanoparticles; preparing an aqueous solution of ethanol containing Zn ions, Ge ions and Mn ions according to a stoichiometric ratio of corresponding elements in the chemical formula of Zn drying the precursor to obtain a gel, then grinding and pre-calcining the gel at 400° C.-600° C. for a period of 1-6 hours to obtain solid matters; calcining the solid matters at 600° C.-1400° C. for a period of 2-10 hours, then cooling to obtain a germanate luminescent material having a general chemical formula of Zn
