Abstract—Specimens composed of Zr_{0.95 – x}Y_0.05O₂:$null$ (x = 0.01–0.15) are synthesized in a muffle furnace and activated by thermal treatment in an electromagnetic field of the microwave range. The conditions for the activation and concentration of Eu³⁺ in phosphor are optimized. Microwave heat treatment results in the growth of grains, reduces microstresses, and increases the fluorescent brilliance of the specimens by a factor of 2.4.
