| Outline of Final Research Achievements |
Electronic states of polystyren nano particle (PSNP) whose diameters are 50-500 nm and surface modificated PSNSP were observed by variable-incidence-angle (VIA) measurement of attenuated total reflectance spectroscopy in the far-ultraviolet region (ATR-FUV). The VIA-ATR-FUV has enabled us to measure the FUV spectra for solid samples without peak-saturation by nitrogen gas purge, and to study the variation in the depth from the surface. In order to arrange the PSNP on the surface with regularity, spin coater was used to form films. The spectra of spin-coated PSNP film could be measured with good reproducibility. It was found that PSNP with larger diameters than wavelength are strongly affected by the real part of refractive index, that is effect of scattering, on the other hand, the spectra of the smaller nano-particle was similar to that of the uniform PS film. The variation in the depth were analyzed by using FDTD method of electromagnetic wave.
