3D Printing of Multi‐Layer Diffraction Gratings for Additive Mixing of Structural Colors (Small 22/2026)
Source abstract
Abstract
Structural Coloration In the Research Article (e14857), Jung Woo Lee, Jaeyeon Pyo, and co-workers illustrate 3D-printed multi-layer nanowire diffraction gratings for advanced structural coloration. A nanoscale nozzle directly writes orthogonally aligned nanowire arrays for illumination angle-selective light diffraction. Superimposing these gratings enables additive colour mixing to produce extra-spectral colours, allowing a significant increase in pixel density for multi-channel colour displays.
