  Silver (Ag) nanoparticles play a significant role in nanomaterials science and technology due to many peculiarities. One of the main characteristic of Ag nanoparticles is the occurrence of surface plasmon resonance (SPR) due to the collective oscillation of free electrons in visible region. Due to this ...  Read More

  Optical properties of Au metal nanoparticle have been studied in terms of extinction (scattering+absorption) at the resonance wavelength from UV to IR region. For the spherical geometry having radius 10nm, local electric field intensity distribution were studied at wavelength 615nm. This enhanced field ...  Read More
