Исследование оптических характеристик керамики на основе иттрий-алюминиевого граната, активированной оксидом церия

Abstract

The study of the optical characteristics of ceramics based on yttrium-aluminum garnet with the addition of 0.03 to 2 wt. % cerium oxide were carried out in this work. Ceramics were made by spark plasma sintering from powders synthesized by reverse deposition, isolated by filtration and spray drying methods. Studies have shown that reflection is not observed in the ultraviolet range for all samples, the maximum value of the reflection coefficient of all samples corresponds to a wavelength of 450 nm, which is typical for the visible wavelength range.
