Abstract:
A tris (2-thenoyltrifluoroacetonato (TTA)) (monophenanthroline (Phen)) Europium (III) (Eu(TTA)3(Ph3PO)2) organic compound was synthesized. Upon excitation with ultraviolet light the material has an abundant photoluminescence (PL) in the red field of spectrum. The experimental results of PL and its kinetics were analyzed using the theory of Judd-Ofelt's parametric method and from which were obtained the lifetime τ, the efficiency η and the probability transitions of the electrical dipoles.
