P‐64: Improvement in Inkjet Printed Green QLED Efficiency
SID Symposium Digest of Technical Papers, 2021There is no doubt that TFB as HTL layer in QLED show predominance in presuming long lifetime devices, however, it is negatively affected by QD solvent in ink jet printing. Herein a thin layer of Tris(4‐carbazoyl‐9‐ylphenyl) amine (TCTA) was deposited between the QD and HTL to prevent QD solvent permeating into the TFB layer.

Structural Properties of QLED Based on Hybrid Quantum Dots
Chinese Journal of Luminescence, 2017In order to study the structure and properties of QLED based on hybrid quantum dots, QLED devices were prepared using red light quantum dots and green light quantum dots as the light-emitting layer, and their properties were characterized. The structure of the device fabricated was ITO/PEDOT:PSS/poly-TPD/hybrid QDs/ZnO/Al, in which three kinds of ...
