The absolute quantum yield and lifetime of 5Do → 7Fj luminescence of Eu3+ ion in europium complexes with fluorinated β diketones has been measured on excitation of luminescence in the UV So → Si absorption band of the ligand in the temperature range 77-365 K. Based on the analysis of the experimental dependences obtained and solution of the balance equations for stationary and nonstationary cases, we have developed a new approach to the determination of the scheme and rate constants of actual transitions. The rate constants of all processes of electron excitation energy conversion have been determined. The role of the state with charge transfer in these processes has been revealed.
