Abstract
The present invention provides a germanate luminescent material, a general molecular formula thereof being ZnGeO:Mn,M, wherein M is selected from at least one of Ag, Au, Pt, Pd, and Cu metal nano particles; 0<x≦0.05; M is doped in ZnGeO:Mn, and y is a molar ratio of M to ZnGeO:Mn, 0<y≦1×10. The metal nano particle M is doped in a germanate luminescent substrate of the germanate luminescent material, and the metal nano particle M improves internal quantum efficiency of the luminescent material so that the germanate luminescent material has a high luminescent intensity. Also provided is a preparation method for the germanate luminescent material.
