[Frontispiece] Structural Color Palettes of Core-Shell Photonic Ink Capsules containing Cholesteric Liquid Crystals

Title:  [Frontispiece] Structural Color Palettes of Core-Shell Photonic InkCapsules containing Cholesteric Liquid Crystals


Author: Sang Seok Lee, HyeonJin Seo, Yun Ho Kim,* and Shin-Hyun Kim*

Journal: AdvancedMaterials, 2017, Vol.29, 1606894

Abstract

Photonicmicrocapsules with onion-like topology are microuidically designed to have cholesteric liquid crystals with oppositehandedness in their core and shell. The microcapsules exhibit structural colorscaused by dual photonic bandgaps, resulting in a rich variety of color on theoptical palette. Moreover, the microcapsules can switch the colors from eithercore or shell depending on the selection of light-handedness.
