چکیده انگلیسی
Rare earth (Eu3+) single nuclear chelated with α-methacrylic acid and 1, 10-phenanthroline, as well as the heteronuclear chelated of Eu3+ and La3+ ions, were synthesized. The composition and structure of the rare earth complexes were confirmed by IR, SEM and XRD. The thermal analysis indicated that the heat-stability was improved. Moreover, the fluorescence spectra proved that the complexes had good fluorescence property. The results showed that it was convenient to synthesize series of europium chelate. The complexes exhibited characteristic fluorescence of europium. ion. The sensitization of La3+ could enhance the fluorescence emission intensity of Eu3+ ion.
