| 中文摘要 | 在970 nmLD激发和Er~(3+)离子浓度几乎不变情况下，研究了Yb~(3+)/Er~(3+)共掺碲钨酸盐玻璃中的能量传递和其上转换发光特性。结果表明：随掺Yb~(3+)浓度的增加，Yb~(3+)/Er~(3+)间能量传递效率也增加，其值在0.52到0.60之间，在Yb~(3+)/Er~(3+)共掺碲钨酸盐玻璃中观察到峰值分别位于533，547nm和668 nm的上转换绿光和红光，它们分别来源于Er~(3+)离子~2H_(11/2) ~4I_(15/2)(533 nm), ~4S_(3/2) ~4 |
| 英文摘要 | The energy transfer and infrared to visible frequency upconversion emission for Yb~(3+) /Er~(3+) co-doped tungsten - tellu-rite glasses were experimentally investigated under the conditions of excited at 970 nm and doped with almost the same content of Er~(3+) ions. With the increase of Yb3+ content, the energy transfer efficiency from Yb~(3+) to Er~(3+) increases gradually and the values of efficiency are all between 0. 52~0. 60. Three visible emission bands are observed in Yb~(3+) /Er~(3+)co-doped tungsten -tellurite glasses excited by 970 nm LD. The three peak values of upconversion emission are located at 533, 547 nm and 668 nm, re-spectively. The red emission originates from ~4F_(9/2) ~4I_(15/2) (668 nm) radiative transition, and the two green emissions originate from ~4S_(3/2) ~4I_(15/2) (547 nm) and ~2H_(11/2) ~4I_(15/2) (533 nm) radiative transitions. The red emission and green emission are a two-pho-non process. The more Yb~(3+) ions in glass, the stronger the green emission intensity and the red emission intensity are, and the larger the ratio of red emission intensity to green emission intensity is. This could be attributed to the courses of energy transfer between the excited state Er~(3+) ions and the excited state Yb~(3+) ions. |
