By employing lithium and nitrogen codoping method, p‐type zinc oxide (ZnO) films have been prepared, and the p‐type conduction can maintain for 207 days. ZnO p–n junctions have been constructed based on the p‐type ZnO. Under the drive of continuous current, obvious emission has been observed from the p–n junctions, and the ZnO p–n junction light‐emitting devices (LEDs) can still work after placing in air ambient for 180 days. Room temperature electroluminescence spectra of the p‐ZnO:(Li,N)/n‐ZnO structured LEDs under continuous current recorded intermittently for 180 days.
