摘　　要：介绍了一种制备含有稀土的磁性发光微球的可行方法。通过沉积包埋作用获得了含铽-甲基丙烯酸-邻菲口罗啉配合物(Tb(MAA)3phen)及四氧化三铁(Fe3O4)的磁性发光微球。透射电镜说明了复合微球为表面粗糙且形状规则的球形粒子;固体荧光检测显示该复合微球表现出稀土铽离子的荧光性能,同时可知该复合微球的荧光强度可达0.5×108;振动样品磁强计得到荧光复合微球粒的比饱和磁化强度在6 emu.g-1左右,并讨论了配合物用量对复合微球荧光性能的影响。A feasible approach to preparation of luminescent/magnetic microspheres with rare earth was reported In the composite microsphere, Tb （MAA）3phen and Fe3O4 were introduced by deposition and embedding with SiO2. The regular-shaped microspheres showed the fluorescence netic properties of Fe304. And its of Tb and the Magfluorescence intensi-ty was able to reach 0.5 × 10^8 which was tested by solid fluorophotometry. The specific saturation magnetization characterized by vibrating sample magnetometer was about 6 emu·g^-1, and the effect on fluorescence properties of different amounts of complex was discussed.
