摘要
稀土配合物光转换剂无一不是Eu(Ⅲ )配合物 ,Eu(Ⅲ )配合物的荧光发射光谱与叶绿素的吸收光谱明显不能吻合 ,叶绿素对Eu(Ⅲ )配合物转换光的吸收少 ,植物光合作用对转换光的利用率低。Eu(Ⅲ )配合物光转换剂加强光合作用的功能需要重新评价。本文对稀土配合物光转换剂的研究提出建议 :进行Sm(Ⅲ )配合物光转换剂的研究 ,取代Eu(Ⅲ )配合物。
Recently, all of the rare earth complexes as light conversion agents were Eu(Ⅲ) complexes. The emission spectra of the Eu(Ⅲ) complexes do not remarkably coincide with the absorption spectra of the chlorophylls, which result in a lower absorptivity of the chlorophylls for the converted light, so the utilization ratio of the light converted by plants is lower. Thus, the enhancement function of the Eu(Ⅲ) complexes as light conversion agents on the photosynthesis should be reinvestigated. From the present research on the rare earth complex light conversion agents the author suggest that the research on the Sm(Ⅲ) complexes as light conversion agents should be conducted to replace the Eu(Ⅲ) complexes.
