The electroluminescence [EL] from a dinuclear-gold(I)-chlorate compound containing bridging phosphine ligands [Au2]dppm(Cl2) as emitting layer is reported. Devices with a structure Al/Au2(dppm)Cl2 /indium-tin-oxide demonstrated a uniform emission under the driving voltage below 1 V. The EL emission was from triplet excited state and the emission color of the device was found to depend on the deposition rate of Au2(dppm)Cl2, which can be explained as the different aggregation forms of the stacking compound in the deposition process.
