摘要: A Sm3+ complex, tris-(2-thenoyltrifluoroacetone) mono-1,10-phenanthroline-Sm3+ [Sm(TTA)3(Phen)], can be easily integrated in situ via covalent functionalization to surface-carboxylated graphene oxide (GO-COOH) from a ethanol solution. The containing material has been comprehensively characterized Fourier transform infrared spectra, X-ray photoelectron spectroscopy, UV–Vis absorption luminescence transmission electron microscopy, powder diffraction, thermogravimetric analysis (TG and DTG). integration of rare earth complexes (RE) onto GO-COOH, as well the individual nature hybrids, is confirmed. GO-COOH with high load capacity integrate more RE than GO. brilliant optical properties GO-COOH-RE complex hybrids make them promising candidates applying many practical fields, such biomedical applications.
