Efficient Blue Organic Light-Emitting Diodes with Graded Hole-Transport Layers

Abstract

Using a derivative of the blue-emitting polyfluorene (see the graph for the output spectrum and the inset picture for the color), efficient devices exhibiting a power efficiency close to 2.7 cd A−1 at 100 cd m−2 light output were realized.
