High-intensity fs-laser pulses permanently change the form of silver nanoparticles in glass and result in optical dichroism. Optical and small angle X-ray scattering experiments are shown which clarify the 3-dimensional shape of the resulting particles.
By studying luminescence and extinction spectra, combined with thermal treatment, novel information was obtained about the processes occurring during deformation of spherical Ag nanoparticles in soda-lime glass upon irradiation by intense fs laser pulses. The results give evidence that the nanoparticles are ionized by the laser pulses, and rather high local concentrations of Ag + ions are...
