AbstractEu3+complex with 1-(2,6-dihydroxyphenyl)ethanone in the solid state has been synthesized and characterizedby elemental analysis, UV–visible, FT-IR and FT-Raman spectroscopies, powder X-ray diffraction, electron emis-sion under femtosecond laser excitation. The stoichiometry and the formula of the studied complex have beenproposed. Its physicochemical properties have been analyzed in terms of the structure and DFT calculations per-formed for the ligand. The luminescence and dynamics of the excited states depopulation have been studiedusing femtosecond laser excitation. Spectral and energetic transformation of femtosecond light impulses hasbeen studied and possibility of the energy transfer between the ligand and the Eu3+electron levels has been analyzed.
