Abstract

A method of preventing an analysis of the material composition of an organic optoelectronic component includes: A) providing an organic optoelectronic component having a functional component part and a camouflage layer, and B) determining an overall analysis spectrum of the organic optoelectronic component by IR or X-ray radiation, wherein the overall analysis spectrum is composed of a first analysis spectrum of the functional component part and a second analysis spectrum of the camouflage layer, and determination of the first and/or second analysis spectrum from the overall analysis spectrum is made more difficult or prevented so that, due to the camouflage layer, determination of the material composition of the functional component part is made difficult or prevented.
