Spectral profile modification

Spectral Profile Modifications In Metal-Enhanced Fluorescence... 

This chapter is organized as follows. In Sec. 2.2, we review some basic aspects of the fi-ee-space fluorescence process and of its modification close to metal surfaces (MEF). These concepts are then extended in Sec. 2.3 to discuss the various mechanisms of spectral profile modification that can be expected in MEF conditions. Experimental demonstration of some of these concepts is...

Figure 2.2 Predictions of spectral profile modifications in MEF for a few model cases. Spectra are shown in terms of Raman shift (equivalent to COg ), assuming a laser excitation at 633 nm. All spectra are normalized to 1. (a)...

Rad( s)- These results provide a qualitative overview of what to theoretically expect in terms of Spectral Profile Modification (SPM) ... 

We will present results following this approach in this section. These will be largely based on the work presented in Ref [1]. There have not been, to our knowledge, any other dedicated experimental studies of this aspect of MEF to date in the literature. Small spectral profile modifications were however occasionally reported as part of other studies [11, 14], but have not been analyzed in depth. 

One possible approach to evidence strong spectral profile modifications under MEF conditions is to take a given fluorophore (fixed ( 5)), and vary the radiation enhancement factor profile The MEF spectral... 

The spectra in Fig. 2.7 also flirther confirm the possibility of large spectral profile modifications in MEF conditions.
