In Situ "Doping" Inverse Silica Opals with Size-Controllable Gold Nanoparticles for Refractive Index Sensing

We report the fabrication of inverse SiO2 opals “doped” with gold (i-Au-SiO2-o) nanoparticles (NPs) via a co-self-assembly method combined with subsequent removal of polystyrene colloidal spheres by calcination. The resulting i-Au-SiO2-o films demonstrate long-range ordering with uniform distribution of ligand-free Au NPs. The size of Au NPs can be tuned from 6 to 30 nm by varying the calcination temperature. The as-prepared i-Au-SiO2-o films preserve both localized surface plasmon resonance (LSPR) and Bragg diffraction peaks simultaneously. Both LSPR and Bragg diffraction peaks are sensitive to the refractive index changes of the surrounding medium—an important feature for sensing applications. The method provides a facile and versatile way to fabricate high-quality Au NP “doped” photonic crystals for applications in sensing and others.
