本文介绍了Sm ~(3+)或Dy ~(3+)(0.5mol%)离子掺杂的重金属氧化物(HMO)基锌铅硼酸盐(ZLB)玻璃的分析结果。进行了吸收光谱、发射光谱、寿命、XRD、DSC等光学测量。Sm ~(3+):ZLB的发射光谱为4G 5/2→ 6 H5/2(563 nm),4G 5/2→ 6 H7/2(598 nm),4G 5/2→ 6 H9/2(646 nm),4G 5/2→ 6 H11/2(708 nm),λexc:401 nm(6 H5/2→ 4F 7/2)。在Dy ~(3+):ZLB玻璃中,发现了4F_(9/2)→ 6 H_(15/2)(485 nm)、4F_(9/2)→ 6 H_(13/2)(575 nm)和4F_(9/2)→ 6 H_(11/2)(664 nm)的发射跃迁,其激发波长为447 nm(6 H_(15/2)→ 4 I_(15/2))。给出了与Sm ~(3+)和Dy ~(3+)玻璃发光机制有关的能级图。
Here, we present the results of the analysis of Sm3+or Dy3+(0.5mol%) 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 Sm3+:ZLB has shown the emission transitions of4G5/2→6H5/2(563nm),4G5/2→6H7/2(598nm),4G5/2→6H9/2(646nm),4G5/2→6H11/2(708nm) with λexc: 401nm (6H5/2→4F7/2). In the case of the Dy3+:ZLB glass, emission transitions of4F9/2→6H15/2(485nm),4F9/2→6H13/2(575nm) and4F9/2→6H11/2(664nm) with λexi: 447nm (6H15/2→4I15/2) have been identified. Energy level schemes relating to the emission mechanisms involved in Sm3+and Dy3+glasses have been given.
