Аннотация:In the article, ZrO2–Sc2O3–Eu2O3 powders containing 1–25 mol % Sc2O3 were synthesized by the coprecipitation method and heat-treated at 500, 750, and 1200 °C. The crystal structure of the synthesized samples was studied depending on the concentration of the stabilizing additive and the annealing temperature using Raman spectroscopy. The local structure of the samples was evaluated by the spectral luminescent properties of the Eu3+ ion.
