Abstract

To investigate the relationship between the particle size and the Raman bands of TiO2 nanoparticles, two different size- selected samples of TiO2 nanoparticles were investigated using Transmission Electron Microscopy (TEM), High Resolution TEM (HRTEM), X-ray Photoelectron absorption Spectroscopy (XPS), and Fourier Transform Raman spectroscopy (FTRaman). In the Raman spectra, both broadening and shifts of the Raman bands with decreasing particle diameter were observed. In this paper, these Raman shifts are attributed to the effects of decreasing particle size on the force constants and vibrational amplitudes of the nearest neighbor bonds.
