Hybrid Blue Organic Light Emitting Diodes with Fluorescent and Phosphorescent Emitters Along with an Interlayer

In this study, we report hybrid blue organic light emitting diodes (OLEDs) with triple emitting layers (EMLs) composed of fluorescent and phosphorescent emitters along with interlayers. The electrical and optical properties of hybrid blue OLEDs are investigated as a function of the various combinations of EML configurations. In addition, the electroluminescent (EL) spectra of the devices are resolved into their base components to understand the …
