Luminescence properties of complex Tb0.25Eu0.75(TTA)2(N-HPA)Phen

Tb0.25Eu0.75(TTA)2(N-HPA)Phen of Eu3+ with thenoyltrifluoroacetone (HTTA), N-phenylanthranilic acid (N-HPA) and 1,10-phenanthroline (Phen) doped with Tb3+ has been synthesized. Photophysical properties of the complex were studied in detail with IR, DTA–TG, XRD, ultraviolet absorption spectra and fluorescent spectra. The luminescence of Eu3+ complex was enhanced by doping with Tb3+. It is proved by the TG curve that the complex is stable, and we have monitored the spectra of Tb0.25Eu0.75(TTA)2(N-HPA)Phen with different ratios for spin-cast film rpm. It was found that there was an efficient energy transfer process between the ligands and metal ions.
