Facile Synthesis of Monodispersed SiO₂@Fe₃O₄ Core-Shell Colloids for Printing and Three-Dimensional Coating with Noniridescent Structural Colors.

ABSTRACT: Amorphous photonic structures (APSs) with short-range ordered arrangement have attracted great interest because of their wide view angles. However, the presented methods for the APSs color printing and 3D coating on different substrates and curvatures are lack of control. Here, APSs with angle-independent structural colors were fabricated by the self-assembly of SiO₂@Fe₃O₄ core-shell nanostructures, which were prepared by the hydrolysis of Fe(acac)₃ on the silica surfaces. The size of SiO₂@Fe₃O₄ core-shell colloids can be controlled well through the tuning of SiO₂ particle size, whereas the coverage of Fe₃O₄ on silica surfaces can be precisely tailored through altering the mass rat
