Figure 4

Emission spectra of (a) Tb(Bim)3 and TbLa3(Bim)12, (b) Janus microspheres (S3) and composite microspheres, (c) Janus microspheres with various contents of TbLa3(Bim)12 at a 0.1 g Fe3O4 MNP mass (the inserted fluorescent image was derived from Janus microspheres S5, the scale bar is 50 μm) and (d) Janus microspheres with different masses of Fe3O4 MNPs at 0.1 g TbLa3(Bim)12.
