The periodic arrangement adds two additional fluorescence enhancement mechanisms - increased excitation intensity due to SPP excitation (34) and modification of the radiation emission pattern. The latter effect has been referred to as "beaming" (56), or more appropriately for fluorescence, surface plasmon coupled emission (SPCE) (57), and results from the coupling of multiple nanocavities via the interstitial surface regions. 

SURFACE PLASMON-COUPLED EMISSION A NEW METHOD FOR SENSITIVE FLUORESCENCE... 

In this chapter we will focus on fluorescence which couples to plasmon resonances in continuous metal surfaces, resulting in directional and wavelength-resolved emission. For the metallic surface, we used a layer with a thickness of only a few tens of nanometers rather than deposited particles. Such a metallic slide is nearly opaque, with a transmission of about 10 -30 %. The most common preparation of these mirrors is done by vapor-deposition. Surface plasmon-coupled emission (SPCE) appears to be a reverse process of surface plasmon resonance (SPR) as seen in the angle-dependent absorption of thin metal films.

One of the most exciting developments with SPR is the development of coupled analytical techniques with surface plasmon resonance. While many other coupled analytical techniques such as LC-MS and GC-MS are well practiced in routine work, little research has been done coupling SPR to other analytical tools until very recently. The most promising coupling technique continues to be SPR-mass spectrometry (MS) and LC-SPR-MS. LC-SPR and SPR-fluorescence (SPFS) have gained considerable attention in recent years. We briefly review these hyphenated techniques and discuss their prospects in future SPR measurements.
