Abstract
Localized surface plasmon resonance wavelength depends on intrinsic and environmental factors of nanoparticles. One of the most important factors is the shape of nanoparticles. The effects of nanoparticles shape on the surface plasmon resonance wavelength shift are simulated and investigated. We have observed that the sensitivity of single cylindrical nanoshell with inner and outer radiuses of 20 and 25Â nm and length of 70Â nm is 509Â nm/RIU while the sensitive nature of nanogear with the same size is 603Â nm/RIU. It is nearly four times the sensitivity of solid spherical nanoparticles and two times the sensitivity of solid nanorods.
