Solid-State Synthesis and Characterization of Nanocrystalline La(Oxin)3·3H2O Under Ultrasonication
Under near ambient temperature and ultrasonication, the La(Oxin)3·3H2O (lanthanum 8-quinolinolate) nanocrystallite was synthesized by solid-state reaction. The solid phase was characterized by powder X-ray diffraction (XRD) and electron diffraction (ED). The particle size, its distribution, and morphology of the prepared nanocrystallite were observed by transmission electron microscopy (TEM). Results showed that the product was nanocrystallite with a uniform particle size and with an average size of about 50 nm. During the synthesis of La(Oxin)3·3H2O nanocrystallite, the types of factors influencing the final product under different solid-state reaction conditions such as reactant, changing the proportions of reactant, addition of inert substances, mixing of trace solvent or surfactant and time of porphyrizing was also observed. This new method is easy to carry and has the advantages of simple processes such as synthesis, high yield, high selectivity, uniform particle size distribution, controllable size and less pollution. It also can prevent or reduce the phenomenon of agglomeration of the liquid phase and the phenomenon of particle agglomeration caused by intermediate step and high-temperature reaction.
