Abstract

Quantum dot light-emitting diodes (QD-LEDs) have recently attracted much attention due to its highly saturated emission color and the capability of tuning the emission color by means of engineering its size. In this letter, an allinorganic light-emitting diode based on colloidal core/shell CdS/ZnS nanocrystal quantum dots (QDs) emissive layer sandwiched between p-type NiO and n-type ZnO is reported. NiO and ZnO layers are deposited by means of the lowcost spin coating technique. The device showed a rectification behavior and QD light emission with the electroluminescent emissions at 605nm.
