Polymer light-emitting devices from nanostructured poly(3-octadecylthiophene) film obtained by electrophoretic deposition from a colloidal suspension have been prepared. The atomic force microscope image of the film surface shows a pronounced nanostructured morphology. Despite the porosity of the nanostructured polymer film, the device made by the simple vacuum deposition of a metal cathode on the polymer film deposited on an transparent electrode emits light. The nanostructured conjugated polymer films have no macroscopic porosity. The inhomogeneous emission was found to be a result of the roughness of the polymer film. Since the emission pattern is neither controllable nor duplicable, this device can be used as artificial fingerprints for polymer smart cards.
