Fig. 14From: Strong coupling in plasmonic metal nanoparticlesStrong coupling in tip-based nanoparticles. a The strongly confined ∣Ez∣ fields in a single CdSe/ZnS QD with Al2O3 layer and Au tip. b TEPL spectra of different single QDs with varying coupling constant and Rabi frequency. TEPL spectra were obtained with varying c lateral tip-QD distances and d vertical distances. Reproduced with permissions from [104]Back to article page
