説明:

We established a universal modular strategy for synthesizing functional hybrid nanosheets and subsequently constructed multi-functional photonic crystals via their self-assembly. By electrostatically integrating negatively charged titanate nanosheets with positively charged nanoparticles, including gold nanoparticles, gold nanorods, and fluorescent silica nanoparticles, we successfully synthesized functional hybrid nanosheets. The enhancement of electrostatic repulsion between these nanosheets enabled the formation of multi-functional photonic crystals with modularly integrated structural color, plasmonic absorption, and fluorescence. Finally, we demonstrated three-dimensional visualization of the photonic nanostructures using confocal microscopy and reversible modulation of the optical properties using magnetic fields and light. This work provides a versatile platform for designing next-generation smart photonic materials with integrated functionalities.
