dc.description.abstractStrong electromagnetic enhancements can be provided by noble metal nanostructures via the excitation of localized surface plasmons using light. This has aroused great interest in the field of utilizing the unique optical properties of metal nanoparticles, especially gold or silver, for SERS applications. In this project, the theoretical effect on the LSPR activity of Au nanoparticles was investigated. The condition of nanoparticles of different lengths and morphology under light radiation was simulated by Discrete Dipole Approximation (DDA) method, and their extinction signals were then analyzed. It is found that different choice of parameters and shape would result in variations in plasmon resonance peak positions and the amplitudes. The influence of such variations will be discussed. From the simulation result, it is shown that simulations are essential for studying the optical properties of the nanoparticles under various conditions, and also for correctly interpreting experimental data and modifying the nanoparticles for optimal use in future applications.en_US
