Figure 2From: Controllable photoluminescence enhancement of CdTe/CdS quantum dots thin films incorporation with Au nanoparticles UV–vis absorption spectra and PL spectra of Au NPs/QDs nanocomposite films with different number of PDDA/PSS bilayers. (a) The absorbance spectra of samples. (b) The PL spectra of samples. The inset showed QDs film’ PL intensities versus the number of spacer layers between Au NPs and QDs.Back to article page
