Abstract: The transparent stiff sodium borosilicate gels containing CuCl were synthesized by using tetraethyl
orthosilicate/ethanol, boric acid/ethanol, sodium ethoxide/ethanol, CuCl/HCl as precursors. The CuCl-doped glasses were prepared by
densification of the stiff gels at 500~600℃. The effects of the concentration of CuCl and the chlorhydric acid on the sol, gel
and glass were investigated, and the preparation mechanism of CuCl-doped sodium borosilicate glasses were discussed also. The photoluminescence
properties of the glasses were studied. The third order nonlinear refractive index of such glasses were characterized by Z-scan method at
1.33μm, and n2 measured was 3.3×10-20m2/W.

Key words: CuCl, sol-gel, Na2O-B2O3-SiO2 glass, third order nonlinear refractive index
