Metal nanostructures are of considerable interest due to the unique mechanism by which these structures interact with light. Extensive work has been reported on the synthesis, modeling, and utilization of various morphologies of plasmonic structures. Recently, the synthesis of highly crystalline Ag:SiO<sub>2</sub>:Ag core:spacer:shell particles of varying geometries by the hydrogen reduction method was reported. Herein, we report the effect of spacer thickness and shell morphology on the coupling of plasmon modes and thus the relative ratio of plasmon relaxation pathways.  Likewise, the relationship between CSS particle geometry, analyte molecule placement, SERS and SEF enhancement factors, and analyte emission lifetimes is explored.
