Abstract:
1. A light-emitting element comprising: an anode; a first layer including a cluster in direct contact with the anode; a second layer comprising a substance having a light-emitting property over the first layer; a third layer comprising an electron-donating substance and a compound having an electron-transporting property over the second layer; a fourth layer including the cluster over and in contact with the third layer; and a cathode over the fourth layer, wherein the cluster comprises a dimolecular body and a molybdenum oxide, wherein the dimolecular body is formed from a first arylamine compound and a second arylamine compound arranged in parallel, wherein each of the first and the second arylamine compounds comprises two arylamines, wherein each of the two arylamines has one phenyl group and two aryl groups bonded with a nitrogen atom; wherein the two arylamines form a biphenyl bond through the respective phenyl groups, and wherein the dimolecular body is coordinated to the molybdenum oxide.
