Abstract
- Owing to the unique optical properties, core-shell nanoparticles are receiving increasing attention from the scientific community and have widespread applications in high-resolution optical imaging, enhanced light absorption in photovoltaic and photocatalysis etc. The present research work reports the synthesis of Au-Ag core-shell nanoparticles based nanocomposites with polyvinyl alcohol (PVA) as the host matrix. Morphological analysis of the prepared nanocomposites was carried out using high resolution transmission electron microscopy (HRTEM). Further UV-visible absorption spectroscopy was utilized to study the optical properties such as absorption coefficient (α), optical energy gap (Eg) and Urbach’s energy (Eu) of thus synthesized Au-Ag core-shell PVA nanocomposite.
