Surface Plasmon Excitation and Related Methods

Fundamentals. Surface plasmons (SP) can be used to monitor optical properties of metal and semiconductor surfaces. For introductory overviews, see [969, 970]. Surface plasmon field-enhanced light scattering (SPFELS) is observed when an interface is illuminated by light under conditions stimulating surface plasmon excitation as reported [971]. 

Applications in electrochemistry similar to surface plasmon (resonance) spectroscopy are treated in the previous sections. Photoluminescence associated with surface plasmons is treated in Sect. 5.6.4. 

Instrumentation. The experimental setup is similar to the one used in SPR. An additional photomultiplier mounted at fixed angle with respect to the base of the prism at the solution side of the electrode films is used to detect light scattered from the rough electrode surface and/or the polymer film deposited on the metal film (see Fig. 5.153).
