The positions of the interstitial oxygen atoms in PWO crystals are numerically simulated by.
运用GULP计算软件模拟计算了PbWO4(PWO)晶体中不同位置的填隙氧原子点缺陷的生成能,计算结果表明:当填隙氧原子存在于(WO4)2-的周围时,填隙氧原子点缺陷的生成能最低;进一步运用基于密度泛函理论的全数值自洽DV-Xα方法计算了包含填隙氧原子的PWO晶体的态密度,计算结果表明:当填隙氧处在(WO4)2-的周围时,容易与(WO4)2-上的一个或两个氧离子相互作用形成分子离子O22-或O34-,通过分析这些计算结果,认为PWO晶体中350nm吸收带的出现很可能与晶体中的氧分子离子有关。
