title: [Electroluminescent device based on rare earth terbium complex].
abstract: Rare earth complex TbY(m-MBA)6 (phen)2.2H20 have been synthesized, which were used as emitting materials in electroluminescence. Single-layer devices and bilayer devices with Alq as electron transmission layer have been fabricated. The electroluminescent properties of the devices were studied. The electroluminescent mechanism of the devices was proposed by measuring and analyzing the emission and the excitation spectra of the emissive layer. Y3+ may play the role to promote the energy transfer from ligand to Tb3+ and the possible energy transfer process of the device was preliminarily discussed.
