Figure 3. Molecular radiative energy shifts in the plasmon-QEs systems under dried condition.

Figure 3

Under dried conditions, molecular radiative energy shifts were also observed in the plasmon-QEs systems made of (a) Au nanostar@thin-SiO2@Cy7-SiO2 and (b) Au nanostar@thin-SiO2@Cy7.5-SiO2 using an XploRA PLUS Raman microscope (HORIBA Instruments Inc., Edison, NJ, USA) under a 638 nm diode laser with a power of ~ 1 mW as compared to the control sample made of SiO2@thin-SiO2@Cy7-SiO2 and SiO2@thin-SiO2@Cy7.5-SiO2, respectively.
