Figure 2From: Synthesis and White-Light Emission of ZnO/HfO2: Eu NanocablesTypical TEM image of the ZnO/HfO2:Eu nanocables annealed at 700°C. The insets are the EDS taken from the cable center and the shell, respectively, indicating that the nanocables contain Hf, Zn, and O, the shells contain Hf and O only (a little number of Zn can be ascribed to the interface of ZnO and HfO2)Back to article page
