摘要 以磷酸钠、硝酸铈为原料,P123表面活性剂为模板,采用水热法,通过调节溶液的pH值,来比较不同pH值对合成的六方相磷酸铈材料的微观形貌及其性能的影响,探讨了CePO4纳米材料的形成的机理。通过X射线衍射、透射电子显微镜、Fourier红外光谱和室温荧光光谱对样品进行表征,结果表明:当pH=9时,得到近似颗粒状的CePO4粉体,其平均粒径为20~30nm,而随着pH值的减小,合成的六方相磷酸铈颗粒沿一维方向生长,当pH=1时,合成的六方相磷酸铈为一维纳米材料,其中纳米线的长径比为30~40;荧光发射强度随着pH值减小和纳米线的长径比增大而显著增强,从8247增大为93600。 One-dimension cerium phosphate nanomaterials were synthesized via a hydrothermal method, using surfactant P123 as template, by changing pH values and comparing the influence on the morphology and properties, and a possible mechanism for fabri- cating one-dimension cerium phosphate nanomaterials was proposed. X-ray diffraction, field transmission electron microscope, pho- toluminescence, Fourier transform infrared spectra were used for characterization. The results show that when the pH is 9, nanoparti- cles...
