Inkjet-Printed Quantum Dot/Organic Semiconductor Nanohybrids for Efficient InP-based Quantum Dot Light-Emitting Diodes

The inkjet-printing process will be the critical fabrication process for the electroluminescent (EL) quantum dot light-emitting diodes (QD-LEDs) to meet the needs of industry users. Here, the inkjet-printed InP-based QD/organic semiconductor nanohybrids were applied as an emission layer in the inverted QD-LEDs. Even though the printing process of the nanohybrids was performed in ambient air, the red and green devices show the maximum current efficiency of 9.7cd/A and 10.4cd/A, respectively, with the maximum luminance of over 7400 cd/m2.
