An organic electroluminescence (EL) device doping material which is thermally stable, having a high melting point, and doping with which improves stability of a luminous layer formed as a thin layer. An organic EL device 1 comprises a glass substrate 3, an anode 2 made of transparent indium tin oxide (ITO), an electron hole implanted transporting layer 4 of TPD, a luminous layer 5, and a cathode 6 made of Mg. The luminous layer is made of Alq3 doped with 1 mol % of Al2O (SABF)2 as a metal chelate complex having ligands composed of SABF skeletons. When plus DC voltage is applied to the anode 2 and minus DC voltage, to the cathode 6, the luminous layer 5 emits yellow electroluminescence of 16400 cd/m2 at maximum with 15 V. The external quantum yield was 0.1891 m/W. The luminous layer of the organic EL device is thermally stable and hard to be deteriorated.
