摘要：CePO4 nanowires attached to CeO2 octahedral micrometer crystals have been synthesized on a large scale using, a higher molar ratio of Ce3+ and PO43- by a facile one-step hydrothermal method. The influences of synthetic parameters, such as reaction time, ratios, and types of reagents, on the morphologies and crystal structures of the resulting products have been investigated. The formation process of CePO4 nanowires attached to CeO2 octahedral micrometer crystals is time dependent: CePO4 nanowires are formed first, and then CeO2 grows into octahedral micrometer crystal. It is found that the photoluminescence properties of CePO4 nanowires attached to CeO2 octahedral micrometer crystals are enhanced strongly in comparison with pure CePO4 nanowires due to the synergic effects Of CePO4 nanowires and CeO2 octahedral micrometer crystals.
