Descripción general

Dysprosium(III) oxide (Dy₂O₃) is a rare earth metal oxide known for its chemical and thermal stability, high dielectric constant, and wide band gap, making it suitable for various advanced applications. It is widely used in optical coatings for ceramic lamp envelopes, protective layers for optical components, and as a dopant in superconductors. Additionally, Dy₂O₃ has shown promise in enhancing the dielectric and humidity sensing properties of nanomaterials, as well as in radiation shielding applications.

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
