Abstract: Compositionally “mixed” (yttria-scandia) sesquioxide transparent ceramics doped with erbium ions, ∼7 at.% Er:(ScxY1-x)2O3 (where x = 0–0.445) were fabricated by vacuum sintering at 1750 °C for 5 h using 1.7 mol% ZrO2 as a sintering additive. For this, nanopowders of the same composition obtained by laser ablation and sedimentation were used. The as-prepared nanoparticles (monoclinic sp. gr. C2/m) had a mean size of 20 nm and they were transformed into the stable cubic phase by calcination at 870–1150 °C. The ceramics were of single-phase nature (C-type bixbyite structure, sp. gr. Ia-3). For the (Er0.074Sc0.114Y0.812)2O3 ceramic, the lattice constant was a = 10.5067 Å, the mean grain size – 21.6 μm, the average content of pores – 4.2 ppm and the transmission at 1.1 μm - 81.9%. The X-ray diffraction and Raman studies of ceramics confirmed the existence of a solid-solution composition. With increasing the Sc3+ content in the ceramics, their lattice shrinked, the mean grain size increased and the thermal conductivity decreased from 6.14 to 3.66 Wm−1K−1 at room temperature. The “mixed” ceramics exhibited intense inhomogeneously broadened emission around 2.8 μm making them promising for mid-infrared lasers. © 2023

The reported study was funded by RFBR (Russia) according to the research project No. 21-53-15014 and CNRS (France) according to the project IEA No. 00432. The thermal behaviors (TG-DTA) of the as-synthesized nanopowders were studied at the “Geoanalitik” shared research facilities of the IGG UB RAS. The re-equipment and comprehensive development of the “Geoanalitik” shared research facilities of the IGG UB RAS is financially supported by the grant of the Ministry of Science and Higher Education of the Russian Federation (Agreement No. 075-15-2021-680). The XRD, EDS and thermal properties of ceramics were studied using the equipment of the Center for Collective Use of the North-Caucasus Federal University financially supported by the Ministry of Education and Science of Russia, unique project identifier RF - 2296.61321X0029 (agreement No. 075-15-2021-687).
