Figure 4From: Enhanced photocatalysis by coupling of anatase TiO2 film to triangular Ag nanoparticle island(a) The local field intensity enhancement distribution E/E 0 in the logarithmic scale due to the presence of the equilateral triangular Ag NP island with 120 nm edge lengths and the incident wavelength is 480 nm. (b) The Raman scattering spectra of pure TiO2 film and Ag/TiO2 nanocomposite film.Back to article page
