【 摘 要 】

Noble metal nanoparticles are of great interest due to their tunable optical and radiative properties. The specific wavelength of light at which the localized surface plasmon resonance occurs is dependent upon the shape, size and composition of the particle as well as the dielectric constant of the host medium.Thus, the optical properties of noble metal nanoparticles can be systematically tuned by altering these specific parameters.The purpose of this thesis is to investigate some of these properties related to metallic nanoparticles.The first several chapters focus on theoretical modeling to predict and explain various plasmonic properties of gold and silver nanoparticles while the later chapters focus on more accurately combining experimental and theoretical methods to explain the plasmonic properties of hollow gold nanoparticles of various shapes.The appendix contains a detailed description of the theoretical methods used throughout the thesis.It is intended to serve as a guide such that a user could carry out the various types of calculations discussed in this thesis simply by reading this appendix.
