抄録

Third-harmonic generation measurements have been made for the first time on oriented films of halogen-bridged mixed-valence platinum complexes for the pump wavelength region from 0.6 to 1.0 μm. The |χ(3)(- 3ω;ω,ω,ω)| spectra obtained by the Maker's fringe method show a distinct peak at about 1.8 eV with the peak value of about 4×10-11 esu. From comparison with the electroabsorption data, this peak has been identified with the two-photon resonance peak with the forbidden exciton in the Pt-halogen chains. One-dimensional exciton states in this compound take an important role in the third-order optical nonlinearity, similar to the case in conjugated polymers.
