Hierarchical ZnO/Bi2O3 nanostructures : synthesis, characterization, and electron-beam modification

Hierarchical ZnO/Bi2O3 nanostructures : synthesis, characterization, and electron-beam modification

Two types of ZnO/Bi2O3 nanonecklace heterostructures were fabricated using the vapor-phase transport (VPT) method for the first time. These hierarchical structures were well characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), and transmission electron micro...
