چکیده
|
Silver nanowires are the favorable material in many applications based on their plasmonic double resonance in the visible region. in this paper, thin films of poly-vinyl-pyrrolidone (pvp) doped with silver nanowires (ag nws) in different concentrations have been prepared. the plasmonic imaging system using a high numerical aperture objective lens excite the surface plasmon in these structures. the hot spot results from reflected light intensity of surface plasmon resonance (spr) proved that increasing of concentration of silver nanowires yields to get better hot spot in plasmonic imaging systems by choosing the appropriate wavelength. these obtained results accompanying with third order nonlinear investigations show the ability of samples usage in thermoplasmonic applications.
