In various embodiments, a light-emitting device may be provided including an active structure including a halide perovskite layer. The light-emitting device may further include a first injection electrode and a second injection electrode electrically coupled to the active structure. The light-emitting device may additionally include a control electrode, and an insulator layer between the control electrode and the active structure. The first injection electrode may be configured to inject electrons into the active structure and the second injection electrode may be configured to inject holes into the active structure upon application of a potential difference between the first injection electrode and the second injection electrode. The control electrode may be configured to generate an electric field upon application of a voltage, thereby causing accumulation of the electrons and the holes in a region of the halide perovskite layer so that the electrons and the holes recombine, thereby emitting light.
