Abstract
  Elongated Au nanoparticles (NPs) embedded in silica matrix were fabricated by 100 MeV Ag ion irradiation of 3 MeV Au ion implanted SiO2/Si(100) substrates, annealed at 1050 o C. Electron-beam-induced shape evolution of elongated Au NPs embedded in SiO2 has been studied by high resolution transmission ...  Read More
Tailoring The Size Of Gold Nanoparticles By Electron Beam Inside Transmission Electron Microscope

Y. K. Mishra; S. Mohapatra; D. K. Avasthi; N. P. Lalla; Ajay Gupta

Volume 1, Issue 2 , September 2010, , Pages 151-155

https://doi.org/10.5185/amlett.2010.4116

Abstract
  Au nanoparticles (NPs) embedded in silica matrix were synthesized by atom beam co-sputtering and investigated in detail by transmission electron microscopy (TEM). A study on electron beam induced tailoring of size of Au nanoparticles has been performed in an in-situ TEM experiment as a function of electron ...  Read More
