General description

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.

Application

  • Structural and optical properties of dysprosium oxide thin films: This article examines the chemical and thermal stability, high dielectric constant, and wide band gap of dysprosium oxide thin films (MF Al-Kuhaili, SMA Durrani, 2014).
  • Determination of 8-hydroxy-2′-deoxyguanosine oxidative stress biomarker using dysprosium oxide nanoparticles@ reduced graphene oxide: This research uses dysprosium oxide nanoparticles for the electrochemical oxidation of oxidative stress biomarkers, highlighting its potential in biosensor applications (S Manavalan, U Rajaji, SM Chen, SSP Selvin, 2018).
  • Dysprosium doped copper oxide (Cu1-xDyxO) nanoparticles enabled bifunctional electrode for overall water splitting: This study focuses on the synthesis and application of dysprosium-doped copper oxide nanoparticles as bifunctional electrodes for water splitting (JD Rodney, S Deepapriya, MC Robinson, 2021).
