Abstract

Silver nanoparticles (SNPs), which were stabilized with various alkylthiols, were studied in detail with synchrotron small angle X-ray scattering, UV-Vis spectroscopy and transmission electron microscopy (TEM). UV spectra of SNPs capped with various alkylthiols showed the characteristic surface plasmon bands at ∼ 450 nm. However, the spectral shapes of SNPs with relatively short butanethiols became weaker and asymmetrically broader in the longer wavelength region. Their nanostructures were deliberately characterized by small angle X-ray scattering analysis based on a hard sphere model and TEM results. [ABSTRACT FROM AUTHOR]
