【摘要】 应用Z扫描技术研究了一种富勒烯衍生物盐的自组装薄膜的纳秒非线性折射特性。测得样品在波长532nm处的非线性折射率为n2=-2.22×10-6esu。初步分析表明,大的非线性折射可能起源于薄膜分子的致密有序排列和纳米层状结构。更多还原

【Abstract】 The nonlinear refraction of self-assembled thin film made from trifluoroacetic acid salt of amino-trisubstitued methanofullerene was investigated by using Z-scan at a wavelength of 532 nm. Experimental results show the thin film exhibit self-defocusing, and nonlinear refraction index was measured to be n2=-2.22×10-6esu, which indicates that the material has strong nonlinear refraction. The strong nonlinear refraction results mainly from its dense molecule and nanostructure film.更多还原
