| 摘 要： | 本文首次报导了Tb0.7Gd0.3P5O14非晶在DCM染料激光的激发下,Gd3+→Tb3+的双光子敏化发光现象.在考虑了Judd-Pooler的自旋轨道相互作用三级微扰项之后,较好地解释了实验结果与Axe的二级双光子吸收理论的偏差.

| Abstract: | This paper reports the first observation of sensitized luminescence phenomenon of Tb3+ ion by two-photon absorption of Gd3 + ion in Tb0.7Gd0.3 p5O14 noncrystalline induced by pulsed DCM dye laser. In terms of two-photon absorption, there is a rather large deviation from the prediction of second order theory for 6P7/2,6P5/2 energy of Gd3+ ion. And it is necessary to take into account the contribution of third order spin-orbit interaction. |
