Gd2O3 coatings were formed by detonation spraying for the first time. The coatings were sprayed using Gd2O3 and Gd2O2S as feedstock powders. The spraying was conducted under oxidizing conditions using C2H2+2.5O2 mixture. The Gd2O2S transformed into Gd2O3 during spraying. Coatings 100 μm thick were formed on Al substrates. The velocities and temperatures of Gd2O3 particles accelerated in the barrel of the detonation gun were calculated. During spraying, the Gd2O3 particles experienced melting. Spraying of both feedstock powders resulted in the formation of monoclinic Gd2O3. The coatings demonstrated luminescence when subjected to synchrotron radiation. The coating obtained from the Gd2O2S feedstock powder demonstrated a higher intensity of luminescence than the coating obtained from the oxide. Aluminium plates coated with Gd2O3 derived from the oxide and Gd2O2S feedstock powders were successfully employed as phosphor screens in the beam position monitor at the VEPP-3 synchrotron (Budker Institute of Nuclear Physics SB RAS).
