Stable Plasmonic Coloration of Versatile Surfaces via Colloidal Monolayer Transfer Printing

Abstract

Preparing nanoscale patterns with bright and high resolution structural colors for object decoration remains a challenge. Herein, the authors propose a strategy for fabricating surface‐universal and large‐area photonic crystal monolayer membrane with stable plasmonic coloration based on polydopamine (PDA) modification, self‐assembly, transfer printing, and e‐beam evaporation. In practice, the membrane is achieved with different diameters of silica and polystyrene (PS) colloidal nanoparticles through layer‐by‐layer (LBL) self‐assembled method. The photonic crystals are prepared on the PDA‐coated substrates and experimental spectra of different periodic plasma substrates with 20 nm‐gold‐coating are obtained and analyzed. Based on this, different plasma display patterns are prepared and solvent‐response plasma pattern is fabricated. Compared with traditional coloration method, this method is low‐cost, stable, and surface‐universal and can be used to proceed large‐area plasmonic coloration, which will be promising in the fields of plasma display, optical sensor and anti‐counterfeiting.
