— Highly conductive and transparent CdO thin films have been grown on glass and on single‐crystal MgO(100) by MOCVD at 400°C and were used as transparent anodes for fabricating small‐molecule organic‐light emitting diodes (OLEDs). Device response and applications potential have been investigated and compared with those of control devices based on commercial ITO anodes. It is demonstrated that highly conductive CdO thin films of proper morphology can efficiently inject holes into such devices, rendering them promising anode materials for OLEDs. Importantly, this work also suggests the feasibility of employing other CdO‐based TCOs as anodes for high‐performance OLEDs.
