The ceramics based on cubic (Zr_0.82–xHf_xY_0.17Eu_0.01)O_0.91 with different contents of hafnium were studied. In the work, the elemental composition of the samples was obtained, the cathodoluminescence (CL) spectra and decay kinetics of europium luminescence were studied. The researched showed increase in the content of hafnium doesn’t affect the position and number of observed bands in the luminescence spectrum. The electric dipole and magnetic dipole radiative transitions ratio was estimated for all samples. It’s demonstrated that a decrease in the local symmetry of the europium ion associated with an increase in the hafnium content. It’s shown the ⁵D₀–¹F₁ transition Eu³⁺ decay time doesn’t depend on the hafnium content, but v-aries significantly in different regions of the sample, which can be attributed to the influence of grain bou-ndaries.

研究了不同铪含量的立方体(Zr _{0.82 – x} Hf _x Y _0.17 Eu _0.01 )O _0.91陶瓷。工作中，获得了样品的元素组成，研究了铕发光的阴极发光（CL）光谱和衰变动力学。研究表明，铪含量的增加并不影响发光光谱中观察到的带的位置和数量。估计了所有样品的电偶极子和磁偶极子辐射跃迁比。结果表明，铕离子局部对称性的降低与铪含量的增加有关。结果表明，⁵ D ₀ – ¹ F ₁跃迁Eu ³⁺衰减时间不依赖于铪含量，但在样品的不同区域变化显着，这可以归因于晶界的影响。
