Abstract:
An ultrabright bright quantum dot light-emitting diode (QLED) device and associated method of manufacture. The QLED device includes quantum dots (QD) as emitters and a mixture of metal oxide nanoparticles and alkali metal compounds for simultaneous electron injection and hole blocking to achieve charging balance at high driving current conditions. The ultrabright QLEDs are useful for many light source applications including, but not limited to display, solid state lighting, optical sensor, phototherapy, photomedicine and photobiomedicine.

Claim (Index 16):
The flexible QLED device of  claim 14 , wherein the flexible substrate comprises polyethylene naphthalate, the barrier layer comprises silicon nitride, the cathode layer comprises indium tin oxide (ITO), the electron injection and hole blocking layer comprises zinc oxide (ZnO) nanoparticles and cesium carbonate (Cs 2 CO 3 ), the quantum dot light-emitting layer comprises (CdSe)-zinc sulfate (ZnS)-cadmium zinc sulfide (CdZnS) core-shell-shell quantum dots, the hole transport layer comprises 2,2\u2032,7,7\u2032-tetrakis[N-naphthalenyl(phenyl)-amino]-9,9-spirobifluorene (spiro-2NPB), the hole injection layer comprises Dipyrazino[2,3-f:2\u2032,3\u2032-h] quinoxaline-2,3,6,7,10,11-hexacarbonitrile (HATCN) and the anode layer comprises aluminum (Al).
