Excitation of particl e plasmons in metal nanoallo y

Nanostructures have got lots of propertie s such as optical, magn etic and elec tronic prop erties. These properties c an reveal in different s cience such as chemistr y [۱], biology [۲], physics [۳] and medicine [۴]. Extinction of electromagnetic (EM ) waves is th e most important property in optical viewpoint in nanooptics, nan ophysics a nd nanochemistry. U nderstanding of extinguished energy in nanos tructures sh ould help to physicists and chemists for producing modern tools for sensing and spectroscopy [۵]. T herefore, w e decided t o calculate some optical response o f Gold-Silver ( ି ) spherical nanoallo y by changes of radius, alloy percen tages and r efractive ind ices of medium, numerically. This research sho uld be applied in producing alloy n anosensors in biochemistry, nanoch emistry, biotechnology a nd so on.
