Electroluminescence from Single PVK Layer Organic Light Emitting Diode Using Different Dyes at Different Concentrations

Taher M. El-Agez, Sofyan A. Taya, Ahmed A. El Tayyan, Monzir S. Abdel-Latif & Ahed Afghjani · Physical Science International Journal · 2013

In this work, organic light emitting diodes are fabricated using a single PVK layer doped with a dye. Three different dyes are used: crystal violet, fluorescein, and bromophenol blue. The structure of the single layer device is doped PVK sandwiched between indium tin oxide (ITO)...
