Polarized light over a large spectral region is provided by the novel procedure described in this work. The active material of these light-emitting diodes (LEDs) is formed by two polymer layers that are oriented perpendicularly to each other. The orientation is obtained using the rubbing technique combined with thermal annealing. The Figure represents the electroluminescence (EL) emission from the two-layer LED and its structure (see also inside front cover).
