Figure 2. Ubiquitous molecular radiative energy shifts in diverse colloidal plasmon-QEs systems.

Figure 2

Similar molecular radiative energy shifts for free dyes were demonstrated under pulsed laser pumping in (a) Cy7.5 dyes in DMF ((ΔE = 15 meV) and (b) DyLight 800 dyes in DMF ((ΔE = 13 meV) when compared to under continuous illumination, which were measured under the same condition as in Fig. 1(a). Also demonstrated were the molecule radiative energy shifts in the colloidal plasmon-QEs systems in water (c) for an optical nanoprobe made of colloidal Au nanostar@thin-SiO2@Cy7.5-SiO2 and (d) for an optical nanoprobe made of colloidal Au nanorod@thin-SiO2@Cy7.5-SiO2 as compared to the control sample made of colloidal SiO2@thin-SiO2@Cy7.5-SiO2 under the same experimental condition as in Fig. 1(d).
