摘要

Here, we present the results of the analysis of Sm3+ or Dy3+ (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 Sm3+ :ZLB has shown the emission transitions of (4)G(5/2) -> H-6(5/2) (563 nm), (4)G(5/2) -> H-6(7/2) (598 nm) (4)G(5/2) -> H-6(9/2) (646 nm), (4)G(5/2) -> H-6(11/2) (708 nm) with 401 nm (H-6(5/2) -> F-4(7/2)). In the case of the Dy3+ :ZLB glass, emission transitions of F-4(9/2) -> H-6(15/2) (485 nm), F-4(9/2) -> H-6(13/2) (575 nm) and F-4(9/2) -> H-6(11/2) (664 nm) with lambda(exi) : ->: 447 nm (H-6(15/2) -> I-4(15/2)) have been identified. Energy level schemes relating to the emission mechanisms involved in Sin(3+) and Dy3+ glasses have been given. (c) 2006 Elsevier B.V. All rights reserved.
