Dysprosium carbonates nanoparticles were synthesized by the reaction of dysprosium acetate and NaHCO(3) by a sonochemical method. Dysprosium oxide nanoparticles with average size about 17 nm were prepared from calcination of Dy(2)(CO(3))(3).1.7H(2)O nanoparticles. Dy(OH)(3) nanotubes were synthesized by sonication of
