White electroluminescence of n-ZnO：Al/p-diamond heterostructure devices

doi:10.1088/1674-1056/22/8/088101

Abstract An n-ZnO:Al/p-boron-doped diamond heterostructure electroluminescent device is produced, and a rectifying behavior can be observed. The electroluminescence spectrum at room temperature exhibits two visible bands centred at 450 nm-485 nm (blue emission) and 570 nm-640 nm (yellow emission). Light emission with a luminance of 15 cd/m² is observed from the electroluminescent device at a forward applied voltage of 85 V, which is distinguished from white light by the naked eye.

Keywords: boron-doped diamond film ZnO：Al heterojunction electroluminescence
