摘要
A technique has been developed for infiltrating gold nanoparticles into the pores of synthetic opal using laser ablation and high-temperature annealing, and the reflection spectra of gold-infiltrated opal photonic crystals have been measured. When a halogen lamp was used as a broadband light source, the peak-reflection wavelength of the gold-infiltrated opal was longer than that of the uninfiltrated opal. We calculated the dispersion laws for the two lower photon bands of the synthesized photonic crystals and obtained the corresponding frequency dependences of the refractive index.
