摘要：
Nd-2 (CO3)(3)center dot 8H(2)O particles were prepared in water/oil(W/O) reverse microemulsion composed of cetyltrimethylammonium bromide (CTAB), n-butanol, n-octane, Nd (NO3)(3)center dot 6H(2)O aqueous solution, Na2CO3 aqueous solution by the microemulsion-assisted solvothermal method. The influences of the molar ratio of water to CTAB and the concentration of Nd(NO3)(3) on the morphologies and sizes of Nd-2(CO3)(3)center dot 8H(2)O particles were studied. The structures, morphologies and sizes of the nanoparticles were characterized by X-ray powder diffraction(XRD), differential scanning calorimetry and thermal gravimetric analysis (DSC-TGA), scanning electron microscope (SEM) and transmission electron microscope (TEM). The possible formation mechanism of the morphologies structure of Nd-2(CO3)(3)center dot 8H(2)O was proposed. The Nd-2(CO3)(3) particles with polyhedral, fishtail-like and needle-like shapes were controlledly synthesized via the microemulsion-assisted solvothermal method by regulating the molar ratio of water to CTAB. The size of the needle-like Nd-2(CO3)(3)center dot 8H(2)O particles decreased with increase of the concentration of Nd(NO3)(3).
