摘要 | In this work, the luminescence properties of samarium ions-doped titanium dioxide prepared by the sol-gel process were studied. A strong orange red emission ((4)G(5/2)-(6) H-7/2 (orange) and (4)G(5/2)-H-6(9/2) (red)) ascribed to the electron transitions in 4f(5) configuration of Sm3+ ions was observed upon excitation into TiO2 host. The energy transfer from TiO2 to Sm3+ was verified and the relevant mechanism was discussed. In addition, the impacts of metal ion codopants upon the TiO2:Sm3+ luminescence properties were studied. The results indicated that the central excitation band shifted to blue in the bismuth-codoped materials (0.5-4% in molar ratio), while it shifted to red in the zirconium-cocloped materials. Such materials may find applications in white light-emission diode (LED) and tunable solid lasers. (c) 2007 Elsevier B.V. All rights reserved. |
