采用离子束分析技术和光吸收测量来定量检测 10keV D2+ 辐照下 LiAlO2 单晶的损伤和氘保留情况。沟道几何中的卢瑟福背散射光谱分析表明，晶格原子因 O/Al 比为 2.5 的入射氘离子而发生无序。弹性反冲检测分析表明，所有入射氘离子都保留在其轨迹末端附近，室温下的最大浓度为 0.7 D/Al。无序原子的深度分布几乎与保留的氘原子的深度分布相同。在相同的温度范围内观察到保留的氘原子的释放和离子诱导的色心的湮灭，这有助于形成 5.25eV 的光学吸收带。在氧空位和保留的氘原子之间建立了相关性。
Ion beam analysis techniques and optical absorption measurements were employed to quantitatively examine the damage and deuterium retention in LiAlO2single crystals irradiated with 10keV D2+. Rutherford backscattering spectrometry in channeling geometry revealed that the lattice atoms were disordered by the incident deuterium ions in the ratio O/Al of 2.5. Elastic recoil detection analysis showed that all the incident deuterium ions were retained near the end of their trajectories with a maximum concentration of 0.7 D/Al at room temperature. The depth profiles of the disordered atoms were nearly identical to those of the retained deuterium atoms. The release of the retained deuterium atoms and the annihilation of the ion-induced color centers, which contributed to an optical absorption band at 5.25eV, were observed in the same temperature range. A correlation was established between the oxygen vacancies and the retained deuterium atoms.
