[MEET5-4(Invited)] Enhanced Performance of All-Inorganic QLED using Double Heat Treatment of NiO HTL
QLED, NiO, HTL, Heat Treatment, Current Efficiency
Crystallization heat treatment at elevated temperatures followed by vacuum annealing treatment at lower temperatures was introduced to form a crystalline NiO single phase. With the modification, the luminance and current efficiency of QLED with the NiO HTL was improved significantly.
