摘要	Electroluminescence (EL) and photoluminescence in both the visible and near-infrared spectral range were observed from a holmium(dibenzoylmethanato)(3)(bathophenanthroline) [Ho(DBM)(3)bath]. Five peaks at 580 nm, 660 nm, 980 nm, 1200 nm, and 1500 nm, respectively, were attributed to the internal 4f electronical transitions of the Ho3+ ions. Except for the emissions of the Ho3+ ions, a broadband exciplex emission from 480 nm to 670 nm appeared in the EL cases. The emission intensity of the exciplex at organic interface showed a tendency to saturation beyond a certain driving voltage, while the emissions of the Ho3+ ions kept increasing. This evolution of visible EL spectra was discussed in terms of the extension of the charge recombination zone. The 1500 nm emission corresponding to the F-5(5)-->I-5(6) transition suggests that the Ho(DBM)(3)bath is a potential candidate for optical communications. (C) 2004 American Institute of Physics.
