Effect of doping different dyes in Alq3 on electroluminescence and morphology of layers using single furnace method

► We fabricated light emitting layer by dissolving dyes in common solvent followed by thermal evaporation of dyes. ► Achieving red emissions with a single furnace. ► We employed single furnace for the first time to control the emitting color of OLED. ► The morphology of the films depends on the homogeneity and type of dyes. ► Low cost, homogeneity and effective energy transfer are advantages of this method.
