To investigate the relationship between the particle size and the Raman bands of TiO 2 nanoparticles, two different size-selected samples of TiO 2 nanoparticles were investigated using transmission electron microscopy (TEM), X-ray absorption near edge structure (XANES), extended X-ray absorption fine structure (EXAFS), and Raman spectroscopy. Analysis of the XANES spectra showed that...
The adsorption behaviors of 2,2′-biquinoline (BiQu) and 8-hydroxyquinoline (8HQu) on gold and silver nanoparticle surfaces have been investigated by means of surface-enhanced Raman scattering (SERS) with the detailed vibrational assignment. The aromatic ring of BiQu and 8HQu appeared to assume a perpendicular or a tilted structure with respect to the gold and silver surface from the presence of the...
