Single photon sources are required for a wide range of applications in\nquantum information science, quantum cryptography and quantum communications.\nHowever, so far majority of room temperature emitters are only excited\noptically, which limits their proper integration into scalable devices. In this\nwork, we overcome this limitation and present room temperature electrically\ntriggered light emission from localized defects in zinc oxide (ZnO)\nnanoparticles and thin films. The devices emit at the red spectral range and\nshow excellent rectifying behavior. The emission is stable over an extensive\nperiod of time, providing an important prerequisite for practical devices. Our\nresults open up possibilities to build new ZnO based quantum integrated devices\nthat incorporate solid-state single photon sources for quantum information\ntechnologies.\n
