摘要：

A volatile Eu complex, Eu(TTA)(3)(phen)(TTA=thenoyltrifluoroacetone, phen=1,10-phenanthroline), was synthesized and applied to an electroluminescent (EL) cell structure of [ITO(=indium-tin-oxide)/hole transporting layer/emitting layer (host material=azomethin zinc complex, and dopant =Eu(TTA)3(phen))/MgIn]. The emitting layers were formed by a codeposition technique. A red emission (EL peak wavelength 614 nm) with a very sharp spectral band was observed from the EL cell with 5 wt% Eu(TTA)(3)(phen), and a maximum luminance of 137 cd/m(2) was achieved.
