| 摘 要： | 激光诱导荧光光谱在确定与证实光谱的归属和能量传递研究以及提高检测灵敏度方面,具有很大的潜力。前人有关稀土配合物的激光诱导荧光分析虽能提高测定灵敏度,但很少涉及发光机理和能量传递方面的研究。

| Abstract: | The luminescence mechanism, the energy transfer processes, the effects of ligand con-centration and laser energy on the fluorescent intensities of the dysprosium-trifluoroacetylace-tone-tri-n-octylphosphine oxide (Dy-TFA-TOPO) system were studied using Nd:YAGpumped dye laser and SIT vidicon optical multichannel analyzer. The phosphorescenceemission of TFA was determined first time on room temperature.The Dy-TFA-TOPO--Tween-20 was adopted in the trace determination of dysprosium. |
