ABSTRACT:
An organic light-emitting diode is described in which the anode comprises midfrequency magnetron sputtered aluminum-doped zinc oxide to increase the device stability and to decrease the material cost. Due the novel deposition technique, ZnO:Al film with ITO-like electrical conductivity can be deposited and improved device performance, especially the long-term stability can be obtained which are attributed to the modification of the ZnO:Al conductivity and surface chemistry.
