摘要：
An organic light emitting device composed of: a cathode; a layer including an organic electroluminescent material; a layer including an electron accepting material; an anode capping layer comprising an inorganic material; an anode; and a substrate in the sequence before the cathode or after the anode, wherein the anode capping layer is selected to provide the device with a luminance stability ratio that is greater than 1.
