| Abstract: | A series of lanthanide(Tb3+, Eu3+, Sm3+, Dy3+, Gd3+) complexes with 1,3-diphenyl-4-phenyl-acetyl-5-pyrazolone were synthesized and characterized by elementary analysis, FTIR and UV-Vis spectra. The Eu3+ complex was further characterized by X-ray diffraction. The luminance properties of the lanthanide complexes were studied in detail. Importantly, the triplet energy level of the ligand was measured with reference to the phosphorescence spectrum of its gadolinium complex, and the difference between the ligand's triplet energy level and the excited energy level of lanthanide ion results in different photoluminescences of the corresponding complex. |
