Plasmonic Effect of Gold Nanoparticles Surrounded by Multidielectric Matrices
Journal Title: Mehran University Research Journal of Engineering and Technology - Year 2017, Vol 36, Issue 3
Abstract
Plasmonic materials are the artificially manufactured materials (metamaterials) typically composed of nanostructure noble metals which give the unique optical properties superior to naturally occurring materials. Such plasmonic material has ability to give surface plasmon when electromagnetic light wave interact with free electrons in conduction band of the noble metals. Entirely absorption of light wave is the one of the major property of such plasmonicmetamaterials. Recently, these metamaterials has drawn the attention of scientists because of its wide range of applications in harvesting energy and sensors. These applications are strongly dependent on adjusting the absorption band-width, peak position and absorption intensity. In this work we show that using ultra-thin multicomponent (i.e. Au NPs incorporated in mixture of SiO2 and TiO2 matrix) nanocomposite deposited on optically thick gold film through subsequent magnetron sputtering. Experimental results show that one can broaden the bandwidth and peak position to span Ultraviolet up to near infrared wavelength range
