摘要:

采用sol-gel方法以Na2O-B2O3-SiO2系统玻璃为基体,采用不同浓度的盐酸溶液为CuCl的先驱体溶剂,在500-600℃的温度范围内烧成了掺杂CuCl的钠硼硅玻璃,详细地研究了氯化亚铜的浓度及其先驱体溶剂对溶胶-凝胶及玻璃性质的影响,讨论了CuCl在钠硼硅干胶中的生成机制,研究了烧结条件对干胶转变成玻璃性质的影响,并研究了这种材料的光学性质,首次报道了掺杂CuCl的Na2O-B2O3-SiO2系统玻璃在1.33μm处的三阶非线性折射率,n2=3.3×10-20m2/W.

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
