We propose a scheme to enhance near-UV band absorption of a rutile TiO 2 nanoparticle by placing Au nanoparticles in its neighborhood. The discrete-dipole approximation method was employed to calculate the absorption spectrum of pure rutile TiO 2 and that of TiO 2 mixed with Au nanoparticles. The results indicate that pure rutile TiO 2 has its maximum absorption located in the deep-UV band. With the existence of Au nanoparticles, a significant light harvesting effect occurs, and this maximum shifts to the near-UV band, where usual excitation wavelength falls.
