The complex [Eu(μ2 -OC2 H5 )(btfa)(NO3 ) (phen)]2 ·phen {btfa = benzoyl trifluoroacetone, phen = 1,10-phenantroline} was investigated by registering the emission and excitation spectra of powder samples at room temperature. The emission spectra show metal-centered luminescence bands, which are assigned to internal radi ative transitions of the Eu3+ ion, 5 D1 →7 Fj and 5 D0 →7 Fj (j = 0–4). Overall, the photoluminescence spectra suggest that the europium ions are situated in a low-symmetry environment.enblue lightdinuclear coordination compoundEu(III); photoluminescenceArticle
