Functional differentiation visualized: diverse light-emitting modes in biomimetic microstructures

Abstract

Biomimetic materials of BaCO₃–SiO₂ biomorphs hybridized with organic dyes were developed to visualize the functional differences among various morphologies. The helicoid microstructures with curved-growth exhibit multistage fluorescence coding characteristics, while the conical microstructures with flat-growth visually exhibit white light emission behavior that is visible due to tricolor spectral superposition.
