Solid-state synthesis and characterization of nanocrystalline rare earth compound under ultrasonication

Under near ambient temperature and ultrasonication, the La(Oxin)₃middot3H₂O (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, and the yield rate of nanocrystalline La(Oxin)₃middot3H₂O is approximately 95.9 %. During the synthesis of La(Oxin)₃middot3H₂O 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.
