Cd‐free RGB Electroluminescent Quantum Dot‐LEDs Fabricated by Inkjet and Electrohydrodynamic (EHD)‐Jet Printing in Ambient Air

Cd-free inverted RGB Quantum Dot (QD)-LEDs were fabricated using air-processed inkjet and electrohydrodynamic (EHD) jet-printing without using a glovebox system, featuring a ZnO nanoparticle ETL and QD/organic nanohybrids, respectively.This approach shows the potential for the utilization of the printing process as a sustainable display fabrication method, reducing the material uses and production costs.
