LaPO(4) and CePO(4) nanorods/nanowires with controlled aspect ratios have been successfully synthesized using a hydrothermal microemulsion method under mild conditions. It has been shown that the obtained LaPO(4) has a monoclinic structure, while CePO(4) exists in the hexagonal structure. Uniform nanorods/nanowires with diameters of 20-60 nm and lengths ranging from several hundreds of nanometres to several micrometres were obtained. The aspect ratios of the obtained 1D nanostructures can be fine-tuned by simply changing the [H(2)O ]/[surfactant] molar ratios. The possible growth mechanism of LaPO(4) and CePO(4) nanorods/nanowires was explored in detail.
通过水热微乳液法在温和条件下成功合成了具有可控长径比的磷酸镧(LaPO₄)和磷酸铈(CePO₄)纳米棒/纳米线。结果表明,所得的LaPO₄具有单斜结构,而CePO₄则以六方结构存在。获得了直径为20 - 60纳米、长度从几百纳米到几微米不等的均匀纳米棒/纳米线。通过简单改变[H₂O ]/[表面活性剂]的摩尔比,可以对所得一维纳米结构的长径比进行微调。详细探讨了LaPO₄和CePO₄纳米棒/纳米线可能的生长机制。
