The layer-by-layer (LbL) assembling method is based on alternating adsorption of oppositely charged materials to fabricate multilayer thin films. The LbL method can effectively generate multifunctional thin films by incorporating more than a single functional component into thin films. In this study, we synthesized semiconductor ZnO nanoparticles, of which surface were modified with silane compounds for stable LbL deposition. Fluorophore-labeled polyelectrolytes were also synthesized to attach dye molecules to polyelectrolytes. Then, thin films were fabricated with surface-modified ZnO nanoparticles, pure polyelectrolytes, and dye-labeled polyelectrolytes by the LbL method. The mutual distance between two layers with different fluorophores was adjusted by the spacer of pure polyelectrolyte layers. In addition, the fluorescence resonance energy transfer (FRET) between fluorophores and ZnO nanoparticles was investigated by adjusting their mutual distance in the thin film. |
