Description
Summary:The Metal – Insulator – Metal (MIM) nanocups structure on glass substrate and in water were fabricated by chemical method and sputtering, studied by transmittance properties. The morphology of the sample was studied by Scanning Electron Microscope, and transmittance properties were studies by UV-Vis-NIR, and simulated by Finite Difference Time Domain (FDTD) method. The result showed that MIM nanocups have surface plasmon resonance (SPR) and localize surface plasmon resonance (LSPR) phenomena, that depend on size of Polystyrene (PS) and thickness of metal and insulator layers. The purpose of this thesis is: Deposit monolayer PS nanoparticles on glass substrate ; Fabrication MIM nanocups structure with core of Polystyrene PS nanoparticles ; Study SPR and LSPR phenomenon of Metal – Insulator – Metal nanocups structure on substrate and in water.
