【Abstract】 La2(CO3)3 nanowires were prepared in the nonionic surfactant microemulsion(Triton X-100/cyclohexane/water)system. Transmission electron microscopy (TEM) and selected area electronic diffraction (SAED) were used to characterize the shape and size of the products. The results showed that the pH value and concentration of mother solution, temperature and aging time all could affect the morphology and size of the La2(CO3)3 nanowires. The lengths of the nanowires were more than 10 μm and the diameters were in the range of 30~200 nm.更多还原
