Measurement Of Nonlinear Refractive Index of One-Dimensional Metal Complexes

Abstract

Nonlinear refractive indexes of the dionedioximes metal complexes were measured by a surface plasmon resonance method. Extremely large nonlinear refractive index; -1 . 9~1 0 '~ cm2/W, was obtained for the Pt(dmg)z at a wavelength of 1.06'pm. Index change over was steadily realized without any defect in the sample film. The absorbance of the film at this wavelength is too small to measure. Nonlinear refractive indexes of Ni(dmg)2 and Pd(dmg)2 are about one order smaller than that of Pt(dmg)2. These values are still very large as non-resonant regions.

“…Many square-planar d 8 metal complexes form one-dimensional metal chains in crystal structures. − Low-dimensional electronic materials have unique electrical and optical properties. − Controlling the crystallographic orientation of low-dimensional materials is important for many applications, because anisotropic properties can arise from their crystallographic orientations. The orientation of crystal growth can be controlled via organic molecular beam epitaxy (OMBE). − OMBE is also advantageous for the fabrication of multilayered devices, such as organic light-emitting diodes (OLEDs). , …”

Epitaxial Orientation of Dimethylglyoximatoplatinum(II) on Various Substrates

“…Bis(dimethylglyoximato)platinum(II) (abbreviated Pt(dmg) 2 , Figure ) is known to have large third-order nonlinear optical properties due to delocalized electrons in the one-dimensional metal chain. , Pt(dmg) 2 molecules form one-dimensional metal chains along the c -axis (as shown in Figure ) and grow epitaxially by vacuum deposition on alkali halide substrates. − In the previous works, the one-dimensional metal chains were successfully fabricated perpendicular to the surfaces. However, the epitaxial orientation remained unexplainable by lattice matching.…”
