Kubelka-Munk diffuse reflectance absorption spectra of different samples. ZnO nanorods (open circle), ZnO nanorods decorated with CdS QDs (filled circle), ZnO nanorods decorated with CdSe QDs (open triangle), ZnO nanorods decorated with both CdS and CdSe QDs (filled triangle), and ZnO nanorods grown in an aqueous solution containing CdSe QDs (square). The absorbance spectra of the pristine CdS and CdSe QDs in aqueous solutions used for the NRAs treatment are shown in inset.
