Abstract: In the present study in search of optimal conditions for the synthesis by the method of sparkplasma sintering of YSZ ceramics with REE dopants in various concentrations, in order to achieve a complex of the best optical-luminescent properties, a series of samples synthesized under similar conditions with variations in atmospheric annealing temperatures from 700°С to 1300°C were investigated. Photoluminescence and photoexcitation of ceramic samples were measured at room temperature using a fluorescence spectrophotometer using a 150 W Xe lamp as an excitation source. From the photoluminescence spectra of YSZ ceramics with REE dopants, we can conclude that in samples subjected to atmospheric annealing at 700 ° C in the region of 450 nm there is an intense intrinsic luminescence of zirconium dioxide, and in samples subjected to atmospheric annealing at 1100 ° C in the region of 600 nm there is a characteristic emission band of europium ion. From the photoexcitation spectra of YSZ ceramics with REE dopants, it can be noted that in samples subjected to atmospheric annealing at 1300 ° C, the maximum luminescence intensity is observed, also the maximum luminescence intensity is mainly observed in the sample with a REE content (Eu[2]O[3]) of 0.5 mass%.
