A novel carbazole functionalized bis-β-diketone type organic ligand, 1,1′-(2,6-bispyridyl)bis-3-(9-ethylcarbazole-3-yl)-1,3-propanedione (H2L) and its corresponding lanthanide complexes Eu2(L)3and Tb2(L)3 were successfully prepared. The ligand and complexes were characterized in detail based on FT-IR spectra, 1H NMR and elemental analysis. The observed UV-Vis absorption and photoluminescence properties of the complexes were investigated, it shows that the Eu(III) and Tb(III) ions can be sensitized efficiently by the ligand (H2L) to some exten...
