Abstract
Information science and technology ( IT; Including computer and communication), Biotechnology (BT) and Nanotechnology (NT), are the three main technologies dominant in the 21st century. In nanotechnology, quantum size effects or surface effect (due to enhanced surface to volume ratio) can cause many new and interesting phenomena.
In the literature there is also evidence that addition of small metal particles to semiconductors can enhance the optical properties of these semiconductor ¡Vnanoparticle hybrid systems. In this thesis, an electrochemical method is used to fabricate Au and ZnO nanoparticles.
To characterize the samples we use various techniques like TEM (for the particle size and crystal structure), XRD (for structure, particle size analysis), Absorbance spectroscopy (for analyzing the optical properties of these systems), Photoluminescence (to study the mechanism of internal emission in the ZnO nanoparticles)
On the theoretical part, some calculations based on the Drude model we computed and compared to the experimental absorbance spectrum of the samples.
