Photonic crystals ( PC s) with periodic dielectric structures are capable to control the propagation of photons when photon energy is in the region of photonic band gap. The upconversion luminescence ( UCL ) of nanocrystals coated on the PC s surface can be enhanced by the PC s effects. While surface plasmon resonance ( SPR ) of noble metal nanoparticles ( NP s) is being extensively applied to enhance the UCL properties of nanocrystals. However, the PC s or SPR effect are developed separately for the UCL enhancement. In this work, we present a facile preparation method of the Au NP s embedded inverse opals, which was used as substrates to improve the UCL properties of Na YF 4 :Yb 3+ , Er 3+ NP s. The significant luminescence enhancement of Na YF 4 :Yb 3+ , Er 3+ upconverting NP s was obtained by the coupling between the SPR of Au NP s and PC s effects from Au NP s embedded inverse opals substrates. The finding demonstrated that the Au NP s embedded inverse opals as substrates may be useful for the enhanced UCL of other phosphors, producing novel photonic devices.
