Calculations of 2s^2S1／2—2P^2P1／2,3／2 Transition Energies for Lithium—Like Systems from Na IX to Ca XⅧ

The transition energies (2ss S1/2-2p2P1/2,3/2) of lithium-like systems with nuclear charge from Z=11-20 are calculated by using a full-core plus correlation method.Relativistic and mass-polarization effects on the energies are included as the first-order perturbation corrections.The quantum-electrodynamics contributions to the transition energy are evaluated by using efective nuclear charge.Our results are in excellent agreement with previous theoretical and experimental data available in the literature.     

类镁离子3s^2^1So—3S^3P^3P1（Z=14—103）跃适的相对论多组态研究

利用全相对论性多组态Dirac-Fock平均能级（MCDF-AL）方法系统计算了高剥离镁离子互组合线3s^2^1So-3S^3P^3P1(Z=14-103)光谱跃迁的能级间隔和跃迁几率，计算中考虑了重要核的有限体积效应及Breit修正和QED修正，所得结果和最近的实验数据及理论计算值进行了比较，结果表明，高原子序数的高荷电离子跃迁的互组合线跃迁几率和中性原子的电偶极E1的相当，在ICF和MCF高温高密度激光等离子体中，互组合线跃迁几率过程不容被忽视。

Visible Upconversion Emission in Er3＋—Doped GeO2—PbO—PbF2 Glass

The upconversion fluorescence emission of Er3 -doped 60GeO2-2OPbO-2OPbF2 glass was experimentally investigated under the pump of 976-nm laser diode. The results reveal the existence of intense emission bands centred around 524, 545, and 657nm at room temperature. The green emission at 524 and 545nm is due to the 4S3/2 2 Hll/2→ 4I15/2 transition and the red emission of 657nm originates from the 4F9/2-→4I15/2 transition of Er3 . The quadratic dependence of the green and red emissions on excitation power indicates that a two-photonabsorption process occurs under the 976-nm excitation. The excited- state absorption from 4I ll/2 and the cross relaxation between two Er3 ions in the 4I ll/2 state contribute to the green emission. The red emission at 657nm is attributed to the excited-state absorption and cross relaxation processes in the 4I13/2 level as well as the 4S3/2 level nonradiative transition of Er3 .
