Study of the photoluminescence properties of two-dimensional dye doped photonic crystals based on localized surface plasmon resonance

We introduce the preparation process of two-dimensional coumarin 6 (C-6) doped poly-methyl-methacrylate (PMMA) photonic crystals (2D C-6 PCs) in detail. We also cover the 2D C-6 PC with translucent Ag shells. By analyzing the system of 2D C-6 PCs and hemispherical Ag shells, we find that resonance energy transfer and local surface plasmon resonance (LSPR) can affect the photoluminescence (PL) characteristics of 2D C-6 PCs. When we cover the 2D C-6 PC with translucent Ag shell, there is energy transfer between the 2D C-6 PCS and the hemispherical Ag shells. The data of photoluminescence and the corresponding decay curves reveal that resonance energy transfer and localized surface plasmon resonance could effectively manipulate the PL properties of 2D C-6 PCs.
