摘要
在稀土离子钐中掺入钇,以水杨酸、邻菲咯啉为有机配体合成了一系列的新的三元有机配合物,研究了该系列配合物的荧光性能,并从中探讨了荧光性能随掺杂离子Y的变化规律,结果表明,稀土离子Y的掺入能改变Sm的红光发光强度,在70%含量时达到最佳。Sm-Y系列有机配合物的特征发射峰位于565、600和650 nm处,与植物叶绿素光合作用的吸收红光波段吻合性较好。
A series of tribasic complexes of samarium（Ⅲ） , yttrium（Ⅲ） with 1,10 - phenanthroline （Phen） and salicylic acid （HSal） was synthesized, The product was characterized by fluorescence spectra analysis. Properties of the product was discussed when the mixing amount of Y varied, the best result was achieved when the proper amount of Y can strengthen the red light luminescence of Sm, which comes to the best when mixing amount reaches 70% （mole proportion）Furthermore, the most in fluorescence emission peak of this series of complexes was at 565 nm, 600 nm, 650 nm, which was most closed to the photosynthesis spectra of vegetables.
