%X Using nanosphere lithography and pulsed laser deposition, Au nanoparticles with different height have been fabricated on quartz substrates. The surface images of Au particles were observed by scanning electron microscopy, and the results showed that the prism-shaped Au particles form a periodical array. In the U-V-visible absorption spectrum, strong absorption peaks due to the surface plasmon resonance of Au nanoparticles were observed. Furthermore, theoretical calculation based on the discrete dipole approximation was performed. The experimental and theoretical results show that the absorption peaks of the Au nanoprism shifted to the blue side as the out-of-plane height increases.
