Angle-dependent intensities of DiI at distances of (a) 2, (c) 17, and (e) from the Ag surface. Calculated angular distribution of radiation from monolayer of DiI-SA at distances of (a) 2, (b) 17, and (c) from the Ag surface.
(a) Free-space and SPCE spectra of DiI-SA LB film at distance from the Ag surface. (b) Peak SPCE and free-space intensities (at a particular angle) of DiI-SA LB film as a function of distance from the Ag surface (c) Distance-dependent intensity decays of DiI-SA monolayer into SPCE mode.
(a) Total intensity of emission into SPCE mode as a function of distance from the Ag surface [the scattered plot is the experimental data and the solid line is the theoretical calculation generated by Eq. (2)]. (b) Distance-dependent average lifetime of DiI in the monolayer assembly (scattered plot); the solid and dashed lines are the calculated lifetimes of a monoexponential decaying dye as a function of distance from the Ag surface assuming fluorescence quantum yields of 0.1 and 0.5, respectively.
