【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。更多还原

【Abstract】 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.更多还原
