nteraction of light with plasmonic nanoparticles whose
wavelength is of the order of interacting light wavelength,
have new physics and applications in electronics, optics and
optoelectronics. When the light of wavelength corresponding
to the surface plasmon resonance absorption propagates
through a nonlinear medium metal nanoparticles strongly
absorb visible light due to their surface plasmon resonance in
which the conducting electrons undergo a collective excitation
induced by electric field of visible light. This enhances the local
electric field near and on the surface of metal nanoparticles. The
enhancement of local electric field within themetal nanoparticles,
leads to the formation of an electromagnetic wave. This wave
induces a huge field on the particle surface strongly polarizing the
atoms of the molecules adsorbed. As the electrons of the atoms
vibrate around their center of mass, the induced dipole moment
oscillates at the wave frequency. This will affect the density,
velocity and plasmonic oscillations of the electronic clouds of
each nanoparticle which will improve self-focusing property of
the light propagating through a nonlinear media. Self-focusing
can be tuned by controlling size and shape of nanostructures
that can play a significant role in medical purposes, LEDs, lasers,
sensor, solar cell, photovoltaic and other optical applications. The
Ag@Au nanoparticles are used so that the plasmon resonance
corresponding to excitation wavelength can be systematically
tuned by varying the thickness of the Au-shell. This can help
in increased stability and trapping capability of plasmonic
nanoparticles that will boost the development of numerous
applications in science and technology.
