The performance of the fabricated QLED was measured, using the sputtered ZnO film. The thickness of the ZnO film was varied to control the electron mobility. Consequently, the maximum current efficiency of 3.96 cd/A, and EQE 2.13% was achieved for the commercially available ZnCuInS/ZnS based QLEDs at yellow emission.
