Abstract: One ternary complex of europium with the plant growth regulator HDPHA (2-Hydroxydiphenyl acetic acid) and Phen (1,10-Phenanthroline), Eu(DPHA)3*Phen*2H2O, was synthesized and characterized by the elemental analysis and DTA-TG measurement. The photophysical property of the complex was investigated by means of IR spectra, Raman spectrum and laser-exited, high-resolved excitation and emission spectra as well as time-resolved luminescence spectra. The luminescence spectra reveal four Eu3+ sites with energy difference within 25 cm-1 and local symmetries of C1 or C2 or Cs in the complex. The energy transfer among the Eu3+ sites is observed. The 7FJ sublevel splitting of the Eu3+ ion is discussed.
