摘要：

Presented here are studies of the impact of incident angle on surface-enhanced emission from a dye that is located site selectively on a plasmon-active nanocavity array support. Studies were performed for a surface-active luminescent dye selectively assembled on the top surface or on the walls of the voids of nanocavity array substrates. Results show that emission intensities depend on where the dye is located with respect to the void or surface of the nanocavity array and on the dimensions of the cavity. This was interpreted to arise from the presence of void-localized plasmons and surface-localized and - delocalized plasmon modes.
