Abstract
The invention relates to polymer substrates which are provided with fluorescence features and in which photochemical fluorescence features, i.e. fluorescent structures, are produced by UV irradiation. Thus, fluorophores can be produced in polymer substrates with a low inherent fluorescence by means of suitable UV radiation, which fluorophores display a marked and detectable emission upon being excited with light of a suitable wavelength. If such an irradiation is implemented in a structured manner, emission patterns can be produced in this way in polymer substrates, which emission patterns can be applied for example as recovery grids in fluorescence microscopy. A further application field relates to product authentication which is made possible by the polymer substrates according to the invention provided with fluorescence features.
