- Title:Perchlorate-Doped PEDOT:PEG as an Additional Hole Injection Layer for Quantum-Dot Light Emitting Diodes
- Sang Moo Lee, Jae Eun Cho, and Seong Jun Kang (Kyung Hee Univ., Korea)
Abstract: A thin layers of perchlorate-doped poly(3,4-ethylenedioxythiophene)-block-poly(ethylene glycol) (PEDOT:PEG) was used as an additional hole injection layer for quantum-dot light emitting diodes (QLEDs). Perchlorate-doped PEDOT:PEG was inserted between transparent electrodes and poly(3,4-ethylenedioxythiophene):poly (styrene sulfonate) (PEDOT:PSS), and improved the interfacial contact. The electroluminescent characterizations indicate that increases of current density and luminance at the device with perchlorate-doped PEDOT:PEG. Therefore, double layer structure for the hole injection layer improved the device properties. We will present the origin of the improvements as well as the device characteristics.
