Abstract
A recycling process was easily carried out with just centrifugation to reduce the number of surface defects of ZnO nanoparticles, which are widely used as the electron transport layer in quantum dot light‐emitting diodes. The proposed process was successfully applied to improve device efficiency. Therefore, the results demonstrate that this new method has good potential to reduce waste material and improve material properties.
