STABLE AND ALL SOLUTION PROCESSABLE QUANTUM DOT LIGHT-EMITTING DIODES

Title:

STABLE AND ALL SOLUTION PROCESSABLE QUANTUM DOT LIGHT-EMITTING DIODES

Document Type and Number:

WIPO Patent Application WO/2011/005859

Kind Code:

A3

Abstract:

Embodiments of the invention are directed to quantum dot light emitting diodes (QD-LEDs) where the electron injection and transport layer comprises inorganic nanoparticles (I-NPs). The use of I-NPs results in an improved QD-LED over those having a conventional organic based electron injection and transport layer and does not require chemical reaction to form the inorganic layer, In one embodiment of the invention the hole injection and transport layer can be metal oxide nanoparticles (MO-NPs) which allows the entire device to have the stability of an all inorganic system and permit formation of the QD-LED by a series of relatively inexpensive steps involving deposition of suspensions of nanoparticles and removing the suspending vehicle.
