Morphological Investigation of Gold Nanorods Thin films Grown by DC Magnetron Sputtering

In this letter we report morphological investigation of gold nanorods/Cu3N bilayer thin films. Gold nanorods show localized surface plasmon resonance at two wavelength according to their two principal plasmon absorption bands related to their long and short symmetry axis. A weak transverse plasmon resonance at 430 nm due tom surface plasmon oscillation along the short axis of the gold nanorod, and a wide longitudinal plasmon resonance at 800 nm due to it oscillation along the long axis. The surfaces of thin films were performed by field emission scanning electron microscope. The morphological parameter were studied by Gwyddion software. The gold nanorod absorption at plasmonic wavelength increase with increasing in value of surface roughness
