Abstract:
Experimental results on the bis[(μ2-etoxi)(benzoyl trifluoroacetonato)(nitrato)(1,10-phenantroline)europium(III)]1,10-phenantroline europium(III) coordination complex (hereafter, [Eu(μ2-OC2H5)( btfa)(NO3)(phen)]2·phen) are described. The complex is characterized by photoluminescence (PL) and infrared spectroscopy. Photoluminescence spectra of the complex exhibit strong emission with specific narrow emission bands associated with the 5D0→7Fj (j = 0–4) transitions. The pattern of emission band splitting and the luminescence time decay suggest the presence of at least two different sites of the Eu3+ ion in a low-symmetry environment. The absolute PL quantum yield of the complex is determined to be 49.2%.
