โฆ Synopsis
The third-order non-linear optical properties of evaporated thin films of d* transition metal complexes with dionedioxime have been estimated by third harmonic generation. They formed one-dimensional structures and showed large optical nonlinearities. Resonance effects were observed for respective metal complexes. The maximum xc3) value of 5.6~ lo-" esu was obtained at the near three-photon resonance wavelength for the platinum complex. The delocalized electrons in linear metal chains may be essential for exhibiting large non-linear optical effects.
