This research article describes the synthesis, characterization and third-order nonlinear optical studies of copper(I) complexes [Cu(Br)(N,N'-C12H6N2O2)(PPh3)] and [Cu(I)(N,N'-C12H6N2O2)(PPh3)] abbreviated as [CuBrLPPh3] (1) and [CulLPPh(3)] (2) (L= 1,10-phenanthroline-5,6-dione). Nonlinear optical properties of the complexes are investigated at 532 nm using single beam Z-scan and degenerate four-wave mixing (DFWM) techniques employing nanosecond laser pulses. The complexes show optical limiting behaviour due to effective two-photon absorption. The values of the effective two-photon absorption (2PA) coefficients (beta), third-order nonlinear susceptibilities (chi((3))), and figures of merit (F), are calculated. (C) 2010 Elsevier B.V.
