Abstract

Nanotechnology and the synthesis of nanoparticle systems are attractive in part because of interesting, tunable optical and electrical properties that are not observed with bulk material. Silver nanoparticles (Ag NPs) interact with visible light more efficiently than any other system due to the excitation of plasmon resonances, which are the collective oscillations of the free electron density. These collective oscillations produce an enhanced local electromagnetic (EM) field: this field is responsible for highly-utilized phenomena such as surface enhanced Raman scattering (SERS), enhanced fluorescence, surface enhanced infrared absorption (SEIRA), and many others. Many experiments have been conducted to optimize and tailor nanoparticle properties for various applications and devices. This thesis is centered upon both the stabilization of two-dimensional (2D) arrays of Ag NPs via homopolymer films for further modification as well as the synthesis of core-shell Ag NPs. Characterization techniques include UV-Vis spectroscopy, atomic force microscopy (AFM), and scanning electron microscopy (SEM).
