摘要:An organometallic complex bis(tetra-n-propylammonium)bis(2-thioxo-1 3-dithiole-4 5-dithiolato) cuprate(II) [(C3H7)(4)N](2)[Cu(dmit)(2)] (dmit(2-) =4 5-dithiolate-1 3-dithiole-2-thione) abbreviated as PrCu was synthesized The films of PrCu were prepared using spin coating method The third-order nonlinear optical properties of PrCu in acetone solution and PMMA films were investigated by Z-scan technique at 1064 nm with laser duration of 20 ps The Z-scan spectra reveal that the composite films exhibit large negative nonlinear refractive indices of the order of 10(-15) m(2)/W which are three orders larger than that in acetone solution The nonlinear absorption coefficients were calculated to be 9 416 x 10(-10) m/W For the composite films the figure of merit W and T meet the requirement of all-optical switching devices The experimental results show that the PrCu-doped PMMA films have potential applications for nonlinear optical devices (C) 2010 Elsevier Ltd All rights reserved
