以高纯Y2O3粉末为原料，ZrO2为添加剂，采用真空烧结技术制备了（Yb0.05Y0.95）2O3透明陶瓷。结果表明，ZrO2的引入能显著提高氧化钇陶瓷的透过率，并对其机理进行了分析。3.0at.%在1800°C烧结20h时，ZrO2掺杂（Yb0.05Y0.95）2O3透明陶瓷的透光率最佳。陶瓷组织均匀，无第二相，平均晶粒尺寸为15μm。相对密度为99.68%，近红外波段透过率高达83.7%（达到理论值的98.5%）。研究了3.0at.%研究了ZrO2掺杂（Yb0.05Y0.95）2O3陶瓷。吸收截面、发射截面和荧光寿命分别为1.175×10−20、1.767×10− 20cm 2和0.93ms。结果表明，Yb3+掺杂Y2O3透明陶瓷是一种很有前途的激光材料。
(Yb0.05Y0.95)2O3transparent ceramics were fabricated by vacuum sintering technique using high purity Y2O3powder as starting material and ZrO2as additive. The results indicated that the introduce of ZrO2can improve the transmittance of yttria ceramics greatly and the mechanism was also analyzed. 3.0at.% ZrO2doped (Yb0.05Y0.95)2O3transparent ceramics sintered at 1800°C for 20h had the optimum transmittance. The microstructure is uniform and no secondary phase is observed in the ceramics with the average grain size of 15μm. The relative density is 99.68% and the transmittance in near-infrared band is as high as 83.7% (up to 98.5% of theoretical value). The spectroscopic properties of 3.0at.% ZrO2doped (Yb0.05Y0.95)2O3ceramics were also investigated. The absorption, emission cross-section and fluorescence lifetime have been estimated as 1.175×10−20, 1.767×10−20cm2and 0.93ms, respectively. All the results indicate that Yb3+doped Y2O3transparent ceramic is promising laser material.
