The phenomenon of positive aging has been frequently reported in quantum dot light-emitting diode (QLED). However, the root cause for this phenomenon remains illusive. It is interesting to note that, the commonly used electron transport material in QLED, ZnMgO, has been extensively studied as a resistive switching material.
