Metal nanoparticles are of strong interest for their unusual optical and Raman properties with potential for new and improved device applications. Specifically, the significantly enhanced Raman Scattering enabled by Surface Plasmon Resonance on metal nanoparticles open up the potential for the implementation of very sensitive sensors. It has been demonstrated that Surface Plasmon resonance can be used for the detection of a single molecule. Out of the various metal nanoparticles that have been investigated, the most promising are that made of gold and silver. Metal nananoparticles of gold and silver show strong Raman enhancement in the visible spectral region, making …

The dissertation describes the formation of porous silicon through the pores of porous alumina on a silicon substrate. Porous silicon, by itself, is inherently a non-uniform material that has non-uniform optical and electronic properties. In addition, it is also mechanically fragile material requiring careful material handling. The porous silicon fabricated through the nanosized pores of porous alumina are expected to mitigate these problems, thereby enhancing commercial viability of the device. The porous silicon as well the porous alumina have been synthesized through anodisation for various parameters and also various types of anodizing electrolytes. The porous silicon, so obtained have been …
