Samples in the 5Fe₂O₃·10SiO₂·xY₂O₃·(85-x)ZrO₂ composition where x=5, 10 and 15mol% Y₂O₃ were synthetized and investigated by XRD, SEM, density measurements, FTIR, UV-Vis, EPR and PL spectroscopies. X-ray diffraction patterns confirm the presence of the tetragonal and cubic ZrO₂ crystalline phases in all samples.

The IR data show the overlaps of absorption bands assigned to Zr-O-Zr and Si-O-Si linkages in samples. UV-Vis and PL data indicate higher concentrations of intrinsic defects by doping with Y₂O₃ concentrations. The EPR spectra are characterized by two resonance lines situated at about g∼4.3 and g∼2 for lower Y₂O₃ contents.

合成了x = 5、10和15mol％Y ₂ O ₃的5Fe ₂ O ₃ ·10SiO ₂ ·xY ₂ O ₃ ·（85-x）ZrO ₂组成的样品，并通过XRD，SEM，密度测量，FTIR进行了研究，UV-Vis，EPR和PL光谱。X射线衍射图证实在所有样品中均存在四方和立方ZrO ₂结晶相。

红外数据显示了分配给样品中Zr-O-Zr和Si-O-Si键的吸收带的重叠。UV-Vis和PL数据表明，通过掺杂Y ₂ O ₃浓度可以提高固有缺陷的浓度。EPR光谱的特征在于，对于较低的Y ₂ O ₃含量，两条共振线位于大约g〜4.3和g〜2 。
