Energy level alignment in polyfluorene-based polymer light-emitting diodes (PLEDs) is studied with electroabsorption spectroscopy and cyclic voltammetry (CV). Using an active layer containing a blend of three polyfluorenes, it is found that the built-in potential values are determined by the interplay of the contacts work function and the lowest and highest lying energy levels of the blend components.

Abstract

Energy level alignment in polyfluorene-based polymer light-emitting diodes (PLEDs) is studied with electroabsorption spectroscopy and cyclic voltammetry (CV). Using an active layer containing a blend of three polyfluorenes, it is found that the built-in potential values are determined by the interplay of the contacts work function and the lowest and highest lying energy levels of the blend components.
