Color Identification Mark by Laser Processing of Silver Surface

Abstract:

Coloring silver for decorative purposes and for applying identification marks is an important task. In this paper, we consider a method for coloring silver surfaces using VIS plasmonic response in laser-induced nanoparticles (NPs). An analysis was made of the resulted morphology and chemical composition of nanoparticles obtained with nanosecond laser pulses. The dependence of the size and distribution of silver NPs on the laser exposure parameters is determined. The developed color palette was characterized using colorimetric coordinates.
