Abstract

A dmit^2- salt: [(C₄H₉)₄N]Au(dmit)₂ was synthesized. Its third-order nonlinear optical properties of its acetone solution were investigated by Z-scan technique using a pulsed laser with 28 ps duration and 10 Hz repetition at 532 nm. The third-order nonlinear refractive index n₂ and nonlinear absorption coefficient β of the sample solution were obtained to be about 4.997×10^-12 esu and 1.818 cm/GW at the concentration of 2×10-3 M. The second-order hyperpolarizability for its molecular was estimated to be as large as 2.74×10^-31 esu, suggesting [(C₄H₉)₄N]Au(dmit)₂ is a promising material for all-optical switching.
