摘要
本文研究了DCM染料激光激发下的HoP5 O1 4 非晶在 370～ 5 80nm兰绿波段的上转换发光的动力学过程 ,发现离子间能量传递上转换和步进双光子吸收两种机理都共同参与导致了它们的上转换发光 ,而激发光频率的稍微改变会使其上转换动力学发生很大变化。
The dynamics processes of 370-580 nm upconversion luminescence of HoP5O14 noncrystalline excited by DCM dye laser is reported in this paper. It is found that both mechanisms of energy transfer upconversion among ions and stepwise multiphoton absorption of single ion are involved in the upconversion luminescence, the upconversion dynamics would change greatly when the frequency of pumping laser has a little variation.
