Abstract

The effect of a multiple high power Nd:YAG laser radiation on silver ion-exchanged glasses for coloration application is investigated. Exposure time, laser spot size, energy density and wavelength have been varied in order to modify the size and the distribution of the metallic nanoaggregates which are formed under the laser irradiation. These parameters are directly correlated to the coloration change. Optical absorption spectroscopy has been used to confirm the formation of the nanoaggregates by plasmon resonance apparition and the intensity and the shift of the resonance have been observed with the laser irradiation parameters variation..
