摘要

研究了96 mol.%ZrO2-4mol的发光光谱特性。研究了% eu2o3固溶体。96 mol.%ZrO2-4mol的x射线和发光光谱数据。% eu2o3四边形晶体及其圆差干涉对比光学图像表明晶体中存在单斜相夹杂物。单斜相O2-→Eu3+电荷转移带的最大值出现在96 mol.%ZrO2-4mol。与纯四方相的相应波段相比，%Eu2O3四方晶体向更长的波长移动。结果表明，Eu2+离子在96 mol。%ZrO2-4mol。含有单斜相夹杂物的%Eu2O3四方晶体优先占据单斜相晶格位。基于本工作的结果，可以提出一种快速检测ZrO2-R2O3固溶体（R = REM）中单斜相夹杂物的光学光谱方法。

Optical spectroscopy of ZrO2-Eu2O3 tetragonal solid solutions with monoclinic phase inclusions

The luminescent spectral properties of 96 mol.%ZrO₂-4mol.%Eu₂O₃solid solutions have been studied. X-ray and luminescent spectral data for the 96 mol.%ZrO₂-4mol.%Eu₂O₃tetragonal crystals and their circular differential interference contrast optical images suggest the presence of monoclinic phase inclusions in the crystals.The maximum of the O^2-→Eu³⁺charge transfer band for the monoclinic phase present in the 96 mol.%ZrO₂-4mol.%Eu₂O₃ tetragonal crystals is shifted towards longer wavelengths compared to the respective band of the pure tetragonal phase.We show that _the Eu²⁺ ions in the 96 mol.%ZrO₂-4mol.%Eu₂O₃ tetragonal crystals with monoclinic phase inclusions preferentially occupy monoclinic phase lattice sites.Based on the results of this work, one can suggest a method for fast detection of monoclinic phase inclusions in ZrO₂-R₂O₃ solid solutions (R = REM) using optical spectroscopy.
