Figure 3From: Facile solution growth of vertically aligned ZnO nanorods sensitized with aqueous CdS and CdSe quantum dots for photovoltaic applications Structural characterization of ZnO NRAs grown in-situ in CdSe QD solution. (a) SEM image (inset: higher magnification SEM of several nanorods detached from the Zn substrate); (b) TEM image of a ZnO nanorod from sample in (a); (c, d) HRTEM images of a ZnO nanorod surface with incorporated CdSe QDs.Back to article page
