以磷酸钠、硝酸铈、硝酸镝为原料,P123表面活性剂为模板,采用水热法合成了Dy3+掺杂的六方相CePO4一维纳米粉体材料。表征了样品的相结构和形貌。结果表明:合成的一维纳米丝最长可达1μm左右;掺Dy3+的六方相CePO4一维纳米粒子的形貌与纯CePO4相同,其荧光发射性能在波长为348nm处得到了很大的提高,有的甚至是纯CePO4的3～4倍。随着Dy3+掺杂量的不断增加,其荧光发射强度出现了先增大后减小的变化趋势,其中以样品Ce0.95Dy0.05PO4的荧光发射性能最强。磷酸铈一维纳米粉料以其优异的荧光发射性能,有望在光、电等领域发挥其潜在的应用价值。
Dy3 + -doped hexagonal CePO4 one-dimensional nanopowder materials were synthesized by hydrothermal method using sodium phosphate, cerium nitrate and dysprosium nitrate as raw materials and P123 surfactant as template. Characterization of the sample phase structure and morphology. The results show that the synthesized one-dimensional nanowires can reach a maximum of about 1μm. The morphology of the hexagonal CePO4-doped one-dimensional nanoparticles doped with Dy3 + is the same as that of pure CePO4. The fluorescence emission performance of the obtained one-dimensional CePO4 nanoparticle has been greatly improved at a wavelength of 348nm. Some even pure CePO4 3 to 4 times. With the increase of Dy3 + doping amount, the fluorescence emission intensity first increased and then decreased, and the fluorescence emission performance of the sample Ce0.95Dy0.05PO4 was the strongest. With its excellent fluorescence emission performance, one-dimensional nano-powder of cerium phosphate is expected to exert its potential application in light, electricity and other fields.
