Abstract: We study here the effect of temperature upon the continuum emission and Stokes Raman peak ratios from a monolayer of 4-Aminobenzenethiol molecules prepared on a plamon active nanocavity array from an active spherical cap architecture nanomaterial substrate. Our results show that there is partial recover of SERS spectral profile following heating. Our results show that chemical enhanced b2-type modes are affected differently relative to electromagnetic enhanced a1-type modes and to the continuum emission background.
