At near room temperature and under ultrasonication,nanocrystalline lanthanum 8-quinolinolate was synthesized by one-step solid-state chemical reaction.The solid phase was characterized by powder X-ray diffraction(XRD) and electron diffraction(ED).The particle size and distribution,and morphology of the prepared nanocrystallites were observed by transmission electron microscopy(TEM).The size of the spherical particles was relatively uniform and the average particle diameter was about 40 nm,and the reaction yield was approximately 95.9%.Furthermore,the reaction conditions,such as reactant type and ratio,presence of inert substance,addition of trace solvent or surfactants,and porphyrization time may influence the morphology,particle size and size distribution of the final product.The process is simple easy to operate,resulting a product of uniform particle size distribution and controllable size with less pollution.Moreover,nanocrystallites of quality can be produced with a high selectivity in high yields and little or no agglomeration normally found in reactions in liquid phase.
