Here, we present the results of the analysis of Sm(3+) or Dy(3+) (0.5 mol%) ions doped heavy metal oxide (HMO)-based zinc lead borate (ZLB) glasses. Optical measurements such as absorption, emission spectra, lifetimes, XRD, DSC profiles have been carried out. The emission spectrum of Sm(3+):ZLB has shown the emission transitions of (4)G(5/2)-->(6)H(5/2) (563 nm), (4)G(5/2)-->(6)H(7/2) (598 nm), (4)G(5/2)-->(6)H(9/2) (646 nm), (4)G(5/2)-->(6)H(11/2) (708 nm) with lambda(exc): 401 nm ((6)H(5/2)-->(4)F(7/2)). In the case of the Dy(3+):ZLB glass, emission transitions of (4)F(9/2)-->(6)H(15/2) (485 nm), (4)F(9/2)-->(6)H(13/2) (575 nm) and (4)F(9/2)-->(6)H(11/2) (664 nm) with lambda(exi): 447 nm ((6)H(15/2)-->(4)I(15/2)) have been identified. Energy level schemes relating to the emission mechanisms involved in Sm(3+) and Dy(3+) glasses have been given.
在此，我们展示了对掺杂Sm(3+)或Dy(3+)（0.5摩尔%）离子的重金属氧化物（HMO）基硼酸锌铅（ZLB）玻璃的分析结果。已进行了诸如吸收、发射光谱、寿命、XRD、DSC曲线等光学测量。Sm(3+):ZLB的发射光谱显示了(4)G(5/2)-->(6)H(5/2)（563纳米）、(4)G(5/2)-->(6)H(7/2)（598纳米）、(4)G(5/2)-->(6)H(9/2)（646纳米）、(4)G(5/2)-->(6)H(11/2)（708纳米）的发射跃迁，激发波长λ(exc)：401纳米（(6)H(5/2)-->(4)F(7/2)）。对于Dy(3+):ZLB玻璃，已识别出(4)F(9/2)-->(6)H(15/2)（485纳米）、(4)F(9/2)-->(6)H(13/2)（575纳米）和(4)F(9/2)-->(6)H(11/2)（664纳米）的发射跃迁，激发波长λ(exi)：447纳米（(6)H(15/2)-->(4)I(15/2)）。给出了与Sm(3+)和Dy(3+)玻璃发射机制相关的能级图。
