(Color online) Dispersion curves of the SPs of two infinite layer /binary alloy structures. For simplicity, only the real parts of dielectric functions of different metal alloys are considered.
(Color online) Dependence of (a) plasmonic DOS and (c) Purcell factor of air/ on photon energy and Al mole fraction. The dependence of (b) plasmonic DOS and (d) Purcell factor of air/ on photon energy and Al mole fraction. The thickness of the alloys is .
(Color online) (a) Variation of theoretical Purcell factor (blue circle) and experimental PL enhancement ratio (black square) with Al mole fraction in air/ structure. The lines are for visualization. (b) PL emission ratio (black) and (blue) at spectra for .
