| 摘 要： | 200keV Xe+离子辐照使单晶YSZ由无色透明变成紫色透明，结果表明，能量为200keV，注量为1×1017cm-22的Xe+离子辐照YSZ单晶产生的损伤高达350dpa，在损伤区产生高密度的缺陷，但仍然没有发生非晶化转变。吸收光谱测试结果表明，产生吸收带的注量阈值大约为1016cm-2。注量为1×1016cm-2和1×1017cm-2的样品，吸收带峰值分别位于522nm和497nm。光吸收带可能与Zr阳离子最近邻的氧空位捕获电子形成的F型色心和Y阳离子近邻的氧离子捕获空穴形成的V型色心有关。

| Abstract: | A transparent yttria stabilized zirconia (YSZ) single crystal becomes purple after 200keV Xe+ irradiation. Calculation of TRIM 96 shows that 200keV Xe+ ions cause peak displacement levels of ～350dpa (displacement per atom) at the depth of 30nm in a YSZ single crystal at a dose of 1×1017cm-2, and cross sectional TEM images and diffraction pattern show that there is no amorphization. Optical absorption measurements show that a broad absorption band appears at a dose of 1×1016cm-2. For the 1×1016cm-2 and 1×1017cm-2Xe+ irradiated crystals, the absorption bands are centered at 522nm and 497nm, respectively. The bands are assigned to electrons trapped at oxygen vacancies nearest to Zr cations (F type centers) and to oxygen ions with trap holes adjacent to yttria cations (V type centers). |
