| Abstract: | Nanoparticles were obtained by the reaction of SmCl3·6H2O with sodium borohydride (NaBH4) in the presence of sodium polyacrylate (PAA) with average molecular weight of 5,100 as a capping polymer. The resulting colloidal solution was placed on a Cu grid and characterized by transmission electron microscope (TEM) measurement, which clearly indicated the generation of nanoparticles. The reaction of LaCl3 with NaBH4 in the presence of PAA led to preparation of lanthanum nanoparticles, similarly as samarium nanoparticles. |
