Noble metal nanoparticles corresponding to surface plasmon resonance wavelength are excellent light absorbers. The absorption processes create highly energetic electron (hot electrons) near or on the surface of plasmonic nanoparticles. These energetic electrons enhance the local electric field on the metal nanoparticles that leads to the formation of an electromagnetic wave. This wave strongly polarizes the atoms of the molecule and increase electrons vibration of the atoms. As the electrons vibration increase, the induced dipole moment oscillates at the wave frequency. The induced dipole moment will affect velocity, density of electrons of each nanoparticle which will improve optical property propagating light through a nonlinear medium. The optical property of the material can be tuned by controlling shape and size of nanostructure. The tunable properties play a major role in optical applications such as biosensors, photocatalysis, photovotatic devices, laser technology, energy store devices and other optical applications. Thus the noble metal nanoparticles, whose wavelength corresponds to the wavelength of interact light, have vast application in science and technology.
