Abstract

<abstract abstract-type="main"> <title>Abstract</title> <p>We fabricated highly bright and efficient inverted quantum dot (QD) light emitting by using double charge injection layer with organic electron transport material. Using organic electron blocking layer, the controlled injection of carriers was achieved by cascaded energy levels, leading to the decreasing carrier injection into QDs. The improved performance can be attributed to adjust charge injection into the QD emissive layer and reduce exciton quenching.</p> </abstract>
