    • Rapid Assembly of Magnetoplasmonic Photonic Arrays for Brilliant, Noniridescent, and Stimuli-Responsive Structural Colors
    Authors: Van Tan, Tran; Jeonghyo, Kim; Sangjin, Oh; Ki-Jae Jeong; Jaebeom, Lee;  Advisor: -;  Co-Author: - (2022)

    There are usually trade-offs between maximizing the color saturation and brightness and minimizing the angle-dependent effect in structural colors. Here, a magnetic field-induced assembly for the rapid formation of scalable, uniform amorphous photonic arrays (APAs) featuring unique structural colors is demonstrated. The magnetic field plays a fundamental role in photonic film formation, making this assembly technology versatile for developing structural color patterns on arbitrary substrates. The synergistic combination of surface plasmonic resonance of the Ag core and broadband light absorption of high refractive index (RI) Fe3O4 shell in hybrid magnetoplasmonic nanoparticles (MagPla...
