Mixed single layer-based quantum dot light-emitting diode (QLED) was fabricated using the sputtered ZnO layer, where the substrate temperature was varied from RT to 200℃ to improve the electrical properties and device performances. Maximum power efficiency of 5.01 lm/W, current efficiency of 5.58 cd/A, and external quantum efficiency of 2.41% was achieved for the fabricated QLED.
