摘　　要：以廉价的非荧光稀土离子镧掺杂钐作为中心离子,价廉易得的甲基丙烯酸甲酯(MMA)、1,10-邻菲罗啉(Phen)、水杨酸(SA)为配体反应生成一系列四元配合物SmL*L2Phen(L*=MMA,L=SA)。通过元素分析、X衍射分析、电镜、红外光谱、紫外光谱和荧光光谱对配合物进行了分析和表征。结果表明,稀土离子La的掺入能改变Sm的红光发光强度,在掺入量为70%(质量分数)时达到最佳。Sm-La系列有机配合物的特征发射峰位于582、616和662 nm处,与植物叶绿素光合作用的吸收红光波段吻合性较好。Series of new solid quaternary complexes SmL＊L2Phen（L＊=MMA,L=SA） were synthesized by samarium which adulterated by cheap non-fluorescence lanthanum with the ligands of the cheap and popular methylmethacrylate（MAA）,salicylic acid（SA） and 1,10-phenanthroline（Phen）.The complexes were characterized by elementary analysis,X-diffraction analysis,FTIR,electron microscopy and fluorescence analysis.The results show that：properties of the product was discussed when the mixing amount of La varied.The best result was achieved when the proper amount of La can strengthen the red light luminescence of Sm,which becomes the best when the mixing amount reaches 70%（mass fraction）.Furthermore,most of them in the fluorescence emission peak of this series of complexes were 582 nm,616 nm,662 nm,which were most closed to the photosynthesis spectra of vegetables.
