The invention relates to an organic light-emitting device and a production method thereof. The organic light-emitting device is of a layered structure and comprises an anode conducting substrate, a hole injection layer, a hole transmission layer, a light-emitting layer, an electron transmission layer, an electron injection layer and a cathode layer which are stacked in sequence; electron injection layer comprises a passivating layer, a rubidium compound doping layer and a rhenium compound layer; the passivating layer is made of materials of silicon dioxide, aluminum oxide and nickel oxide or copper oxide. Metal ions in the electron injection layer and a cathode can be prevented from penetrating to an organic layer by the passivating layer in the electron injection layer, an electron trap is formed, and electrons are captured and cannot reach the light-emitting layer. |
