Rare-earth doped CeO 2 solid solution nanorods were successfully prepared via a simple co-precipitation method without surfactants at room temperature and pressure. The products were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The effects of the doping contents, pH values, aging times and the precipitation agents on the structure and morphology were...
Porous ZnO thin films have been prepared on glass substrates via sol–gel method using polyethylene glycol (PEG) as organic template, zinc acetate as precursor, ethanol as solvent and diethanolamine as chelating agent. A model concerning the pore formation was suggested that PEG taking zinc oligomers would exclude the ethanol solvent, which results in the phase separation of this system. The experiment...
