The Sodiun, borosilicate glasses doped with Au particles were prepared by sintering sodium borosilicate transparent bulk gels doped with Au which were prepared by using tetraethyl orthosilicate, boric acid and sodium alkoxide as precursors; ethanol,glycolic methyl ether and ethanol as precursor solvents; hydrochloric acid as catalyst and HAuCla. 4H2O as precursor of Au in Na2o-B2O3-SiO2systems. The effects of contents of HAuCl4. 4H2O on the properties of stiff gels and the conversion mechanisms of gels contatining Au into glasses were investigated in detail. The optical properties and microstructure of gels and glasses containing Au were studied by means of UV-visible absorption spectra and TEM respectively. And the third-order non-linear optical properties of glasses containing Au were characterized by Z-scan technique, the third nonlinear refractive index of glass containing Au (n2) is 8.22×10 -12 esu.
