This work reports spectroscopic and structural investigations of the complexes presenting the formulas [Ln(TTA)3L2], [Ln(DBM)3L], [Ln(TTA)2(NO3)L2], [Ln(DBM)2(NO3)L2] and [Ln(DBM)(NO3)2(HMPA)2], where Ln: Eu3+ or Tb3+, TTA: 2-thenoyltrifluoroacetonate, DBM: dibenzoylmethanate and L: HMPA (hexamethylphososphoramide) or TPPO (Triphenylphosphine oxide). The compounds were characterized by complexometric and elemental analysis and single crystal X-ray diffraction. The spectroscopic properties of the complexes were studied by diffuse reflectance and luminescence spectroscopies. Formation of positronium in the complexes were also investigated. In order to obtain a synergy between theory and experiment, DFT calculations were performed, fo...
