摘　　要：合成了一种新的配位化合物(苄基三乙基铵)双(1,3-二硫杂环戊烯-2-硫酮-4,5-二硫基)-金(BTEAADT).利用旋涂技术制备了该材料与聚甲基丙烯酸甲酯(PMMA)掺杂的复合薄膜,该材料在复合薄膜中的质量分数为1%.采用Z扫描方法,分别测试了该材料的乙腈溶液和该材料与PMMA复合薄膜在波长为1064nm,脉宽为20ps条件下的三阶非线性光学特性.同时还研究了复合薄膜的线性光学性质.Z扫描的结果表明,复合薄膜和该材料的乙腈溶液都具有自散焦效应,非线性折射率都是负值.在实验条件下,两者的非线性吸收效应都是可以忽略的.经过计算得出溶液样品的非线性折射率为-1.459×10-18m2·W-1,复合薄膜样品的非线性折射率为-3.978×10-15m2·W-1.该材料在1064nm处的非线性光学器件方面有潜在应用价值.We prepared a new crystalline nonlinear optical coordination compound,benzyltriethylamine bis （2-thioxo-1,3-dithiole-4,5-dithiolato） aurate（III） （BTEAADT）.A BTEAADT-doped poly（methyl methacrylate） （PMMA） thin film with a mass fraction of 1% was prepared by spin-coating.The third-order nonlinear optical properties of BTEAADT in acetonitrile and a BTEAADT-doped PMMA film were investigated using the laser Z-scan technique with 20 ps pulses at 1064 nm.The linear optical properties of the polymer thin film were also studied.The Z-scan spectra revealed that the polymer thin film sample possessed negative nonlinear refraction and exhibited a similar self-defocusing effect to that found for the solution.In addition,nonlinear absorption was negligible for both systems under the experimental conditions used.The nonlinear refractive index was calculated to be-1.459×10-18 m 2 · W-1 for the solution sample and-3.978×10-15 m 2 · W-1 for the film.These results suggest that this material is a promising candidate for application in nonlinear optical devices such as all-optical switching manufacture at 1064 nm.
