Abstract

Nonlinear-optical nanocomposite materials with a photonic crystal structure were fabricated using block copolymers and gold nanoparticles. By dispersing the gold nanoparticles into the selective microdomains of the block copolymers, we could achieve the enhancement of nonlinear optical properties as revealed by the Z-scan technique. The optical nonlinearities were enhanced by the local field effect and the effect of the periodic distribution of the microdomains filled with gold nanoparticles. Furthermore, the highest optical nonlinearity was achieved by matching the domain spacing of the copolymers with the frequency of the surface plasmon resonance peak of the gold.

TEM images of polymer/PS-Au nanocomposite films: (a) PS/PS-Au (ϕPS100), (b) PS-b-PMMA/PS-Au (ϕPS31), (c) PS-b-PMMA/PMMA/PS-Au (ϕPS10), (d) PS-b-PMMA/PMMA/PS-Au (ϕPS3). Scale bar is 100 nm.

Visible absorption spectra of the polymer/PS-Au nanocomposite films: (a) PS/PS-Au (ϕPS100), (b) PS-b-PMMA/PS-Au (ϕPS31), (c) PS-b-PMMA/PMMA/PS-Au (ϕPS10) and (d) PS-b-PMMA/PMMA/PS-Au (ϕPS3). Control samples are also shown: (e) PS-Au in toluene and (f) PS-b-PMMA without PS-Au. The arrows indicate the SPR peak positions: (a) 527 nm, (b) 527 nm, (c) 537 nm, (d) 542 nm and (e) 527 nm. A SPR peak shift is observed in (c) and (d).

Fig. 3.

The values of the third-order susceptibility, χ(3), of ϕPS100, ϕPS3, ϕPS31 and ϕPS10. Three horizontal lines on each error bar represent the values of χ(3) obtained for three independent Z-scan measurements. The filled circles denote the average values of χ(3). The highest value of χ(3) was observed for ϕPS10, while the lowest for ϕPS100.

Fig. 4.

Polymer concentration dependence of the reflection peak wavelength (a) and χ(3) (b) of the PS-b-PtBMA/PS-Au solutions, and the comparison of χ(3) as a function of the apparent domain spacing of the template polymer solutions with the normalized SPR spectrum of PS-Au (c). (a) Error bars represent the full width at half maximum of the reflection peaks. The marks (triangles and squares) indicate the peak wavelengths obtained by temperature variations at the corresponding polymer concentration from 22 to 26 wt.%. (b) The horizontal lines on the error bars represent the values of χ(3) that were determined by three Z-scan measurements and the filled circles and the triangles denote the average values of χ(3). The upper point (filled circle) at 10 wt.% indicates the χ(3) measured at the part with the iridescent color and the lower point (triangle) indicates that of the part without iridescent color. The results of 22, 24 and 26 wt.% were the results obtained at room temperature for the samples that have the reflection peak wavelength at 513, 524 and 543 nm, respectively. (c) The SPR spectrum intensity was normalized after the subtraction of background coming from band to band transition and surperimposed onto the values of χ(3). The domain spacing was calculated from the reflection wavelength using the volume averaged refractive index and is shown as the upper axis. Three horizontal lines on each error bars represent the χ(3) of the three independent Z-scan measurements and the average values of χ(3) is denoted by the filled circles.
