In this work, we proposed that indium-tin-oxide (ITO)-free, which is the most generally used to a transparent electrode for light applications and displays, semitransparent Ni/Ag/Ni electrode could be applied in flexible blue phosphorescent organic light-emitting diodes (OLEDs). Although the highest electrical characteristics values, such as luminance efficiency and external quantum efficiency, using...
We demonstrate for the first time a large-scale ac plasma display panel enhanced by localized surface plasmon (LSP) resonance owing to Ag nanoparticles. In order to generate plasmon resonance fitted to the blue-emitting phosphor, we deposited Ag nanoparticles on the phosphor layer by a spray method using large-scale fabrication technology. Localized surface plasmon resonance by Ag nanoparticles was...
The recombination dynamic of hole and electron and carrier transport mechanism were studied. We demonstrated a efficient green phosphorescent organic light-emitting diodes (OLEDs) as the doping concentration are varied without hole blocking layer (HBL) and electron transport layer (ETL). In spite of device without HBL and ETL, it is possible to inject the electron from the cathode into the emission...
