Abstract
A modified host material, 2,6-bis(N-carbazolyl)pyridine, (26mCPy), which assisted in enhancing device performance, allowing for the creation of an efficient white organic light emitting diode (OLED) is reported. The basic principle for generating white light from an OLED involves combining light output from multiple emission centers. Devices were fabricated on indium tin oxide (ITO) coated glass substrates. PEDOT-PSS was filtered through a 0.45 μm filter and spin-coated on the substrate. The high quantum efficiency suggested phosphor excimer-based emission to be an efficient process. The benefits of this host are thought to be a more balanced ratio of electron and hole carriers in the emissive region or enhanced charge transfer to the dopant.
