Abstract
A ZnO nanorods structure was grown by the hydrothermal method and interpenetrated with CdTe using the isothermal closed space sublimation technique. The obtained structure was studied by using Scanning Electron Microscopy (SEM) and High Resolution Transmission Electron Microscopy (HRTEM), which confirm the formation of CdTe nanocrystals (NCs). X-ray diffraction shows clearly the interpenetration of CdTe on ZnO nanotubes and their purity. Structural details, in particular concerning the interface between CdTe nanocrystals and the ZnO nanorods, are revealed by the HRTEM images. The obtained structure in this work could have the potential to increase the photon conversion energy by multiexcitonic generation.
