  • Title: Laser implantation of plasmonic nanostructures into glass.
    Author: Henley SJ, Beliatis MJ, Stolojan V, Silva SR.
    Journal: Nanoscale; 2013 Feb 07; 5(3):1054-9. PubMed ID: 23254478.
    Abstract:
    A laser direct-writing method producing high-resolution patterns of gold, silver and alloy plasmonic nanoparticles implanted into the surface of glass substrates is demonstrated, by scanning a pulsed UV laser beam across selected areas of ultra-thin metal films. The nanoparticles are incorporated beneath the surface of the glass and hence the patterns are scratch-resistant. The physical mechanisms controlling the process are investigated and we demonstrate that this technique can be used to fabricate a wide range of plasmonic optical structures such as wavelength selected diffraction gratings and high-density substrates for lab-on-chip surface-enhanced Raman spectroscopy.
