| 摘要 |
The present invention provides a germanate luminescent material, a general molecular formula thereof being Zn 2-2x GeO 4 :Mn 2x ,M y , 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 Zn 2-2x GeO 4 :Mn 2x , and y is a molar ratio of M to Zn 2-2x GeO 4 :Mn 2x , 0<y‰¤1×10 -2 . 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. |
