摘要：

New Ge/SiO2glasses have been synthesized by heating the GeO2/SiO2dry gels under H2gas at 700℃. The resulting fluorescence spectra show that this kind of Ge/SiO2glasses emit strongphotoluminescence at 392 nm (3.12 eV), medium strong photoluminescence at 600 nm (2.05 eV)and weak photoluminescence at 770 nm (1.60 eV) respectively. Possible photoluminescencemechanisms are also discussed based on the results of X-ray diffraction (XRD) and X-rayphotoelectron spectra(XPS).
