Origin of Efficiency Roll-Off in Colloidal Quantum-Dot Light-Emitting Diodes

Origin of Efficiency Roll-Off in Colloidal Quantum-Dot Light-Emitting Diodes

We study the origin of efficiency roll-off (also called "efficiency droop") in colloidal quantum-dot light-emitting diodes through the comparison of quantum-dot (QD) electroluminescence and photoluminescence. We find that an electric-field-induced decrease in QD luminescence efficiency-and...
