Laser synthesis of optical media with silver nanoparticles by nanosecond pulses at air.

Abstract

The present work is dedicated to further development of the laser synthesis method for metal nanoparticles formation at air conditions. On the base of complex investigation of processes taking place during laser erosion of metals by intensive nanosecond pulses the method of silver nanoparticles fluxes is proposed. By the implantation of silver nanoparticles into liquid media (water or solutions of a polymeric base) the transarent media with silver nanoparticles can be obtained (particularly water colloids and modified polimer films). For the aims of investigation of formed polymeric films the complex diagnostics method is used Key words: laser erosion of metals, silver nanoparticles, transmission electron microscopy, absorption spectroscopy, surface plasmon resonance.
