Laser-induced transfer of nanoparticles for gas-phase analysis

Abstract

© 2014 Optical Society of America. An experimental study of laser-induced forward transfer of nanoparticles from a metal-coated glass substrate is presented. Nanoparticles are efficiently removed from the substrates due to transient blister formation. A combination of mass spectrometry, atomic force microscopy studies of the irradiated substrates, and theoretical considerations of temperature distributions and stress in the films during irradiation serves to provide insight into the mechanisms involved.
