Sample and characterization. a Schematic of precision-located single molecule inside nanoparticle-on-mirror (NPoM) plasmonic cavity, with DNAo spacer. b Dark-field scattering of individual NPoMs either uncoated but (with)out molecule of Atto647, or with ParlyeneC coating. c Absorption and emission spectra of Atto647 dye in water. d Energy diagram showing electronic and vibrational energy levels of the single molecule (black), and when coupled to a strong-coupled cavity tuned to the emission wavelength (blue, width indicates light-matter coupling strength)
