Abstract

Laser printing with structural colors arising from nanostructure-light interaction is emerging as a promising technology to address the problem of toxic compounds in conventional coloration methods. Up to date, the best-performing laser coloration techniques rely on ultrafast pulsed lasers. In this work, we introduce an approach for low-power, wide-gamut laser coloration on a pre-processed metamaterial of self-assembled nanoparticles. The metamaterial, with aluminum-coated polystyrene nanospheres, changes color through oxidation layer and deformation shape control, achieved using a focused CW laser with an average power of 10 mW. This approach achieves a 33k DPI resolution on a flexible substrate with the broadest color gamut reported.
