Study on the Synthesis and Morphology Evolution of Nd2O3 Nanoparticles Controlled by Ionic Liquid Surfactant Templates
A novel ionic liquid surfactant template is developed for the synthesis of monodisperse neodymium nanoparticles with different morphologies.The influence of surfactant concentration and type on the preparation process is studied,and various analytical techniques are used to determine the precursor and Nd2O3 nanoparticles.The results show that the addition of surfactants such as Cocoamidopropyl Betaine(CAPB)or 1-tetradecyl-3-methylimidazolium chloride([C14mim]Cl)ionic liquids has a significant impact on the product.As the concentration of CAPB increases from 0 to 20 times the Critical Micelle Concentration(CMC),the morphology of Nd2O3 transforms from short nanorods,nanospheres,irregular flakes,and highly regular leaf shaped nanoparticles to spherical nanoparticles,and the phase of Nd2O3 mentioned above is the same.However,from the perspective of morphology,the Nd2O3 prepared by adding[C14mim]Cl is significantly different from that prepared by adding CAPB.The concentration of surfactants affects the precipitation process,and surfactants form different micelle structures as liquid templates to guide the precipitation reaction.The synthesis process is simple,and ionic liquid surfactants can be used to prepare nanoparticles and assemble nanomaterials with new structures and functions.
