Abstract
Disclosed herein is a quantum dot ink composition for inkjet printing. The quantum dot ink composition comprises a highly viscous polymeric additive. Quantum dots can be ejected by inkjet printing and the concentration of the quantum dots in the quantum dot ink composition can be freely controlled. In addition, the loading amount of the quantum dots can be reduced. Based on these advantages, the quantum dot ink composition can be used as a material for light-emitting layers of a variety of electronic devices. Also disclosed herein is an electronic device fabricated using the quantum dot ink composition.
