Geometrical modifications and tuning of optical and surface plasmon resonance behaviour of Au and Ag coated TiO2 nanotubular arrays

摘要: A protocol for surface structuring and shape modifications of anodized TiO2 nanotubes by controlling the electric field is presented. The size control essential in order to achieve more over optical electronic properties such as effective band gap, light absorption capabilities, photoelectrochemical response, Raman properties, well appearance localized states. plasmon resonance (SPR) study was performed using these newly developed nanotubes. It observed that noble metal treated nanotube assemblies exhibit a ‘slow photon effect’ plasmon-exciton interaction. Such photon’ effect highly advantageous improve (PEC) performance quantum efficiency if plasmonic PEC activity coupled with it SPR region. FDTD simulations tilted suggest maximum confinement can be realized lower bend angle 8° this diminishes when inclination increases further.
