REFLECTIVE FABRY-PÉROT (F-P) RESONANT STRUCTURES AND METHODS OF TUNABLE PLASMONIC COLOR PRINTING

Resumen de: US20260036731A1

Plasmonic color printing by fabricating a Fabry-Pérot (F-P) resonant structure on a substrate. The F-P resonant structure includes a reflective layer, a dielectric spacer layer overlying the reflective layer, and a random metal film (RMF) layer that overlies the dielectric spacer layer and has a nanostructure. The F-P resonant structure is photomodified using a laser, which induces changes in the nanostructure of the RMF layer. These changes are tailored to produce desired changes in the light-scattering and reflective properties of the RMF layer. As a result, by tailoring the photomodifications and the changes it produces, the color-generated by illumination filtered through and reflected from the F-P resonant structure can be tailored to a desired hue.
