Alloying of metals forming linear chains in the one-dimensional metal complexes was performed by use of vacuum evaporation technique. Mixture of two different metal complexes with dimethylglyoxime could be fabricated into a thin film with high transparency. They showed a strong d-p transition band in the visible region, and their peak wavelengths subsequently varied in proportion to the mixing ratio of metal complexes. Their third-order nonlinear optical property was investigated by the third harmonic generation measurements. Obtained third order nonlinear susceptibilities chi(3) are plotted against the linear absorption coefficient ( at the third harmonic wavelength for mixture of Pd (dmg)2 and Pt (dmg)2 with different mixing ratios in the figure. The film containing higher platinum complex showed larger chi(3) values at the same a value.
