Third Order Nonlinear Optical Properties of Benzyltriethylamine Bis(2-thioxo-1,3-dithiole-4,5-dithiolato) Aurate(Ⅲ)
摘要
Abstract
We prepared a new crystalline nonlinear optical coordination compound, benzyltriethylamine bis (2-thioxo-1,3-dithiole-4,5-dithiolato) aurate(lll) (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 -1.459x10-18m2· W-1 for the solution sample and -3.978x 10-15m2·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.关键词
