| 英文摘要 | In this paper, we report the color tuning of Er doped TiO2 upconversion phosphors within a fixed Er concentration using 976 nm semiconductor laser diode excitation. By codoping with Mo, Yb or Li ions in the Er doped TiO2, the green and red upconversion emissions from the H-2(11/2)/S-4(3/2) -> I-4(15/2) and F-4(9/2) -> I-4(15/2) transitions of Er ions were enhanced selectively and the color output of Er doped TiO2 could be tuned by different intensity ratios of green to red emissions. The two-photon absorption processes were responsible for the green and red upconversion emissions of Er-Mo, Er-Yb and Er-Li codoped TiO2 phosphors, and the corresponding enhanced mechanisms were discussed. It is expected that these color tuned phosphors within a fixed Er concentration have great potential for applications in biology, displays and other optical technology. |
