Method for producing an intelligent label, intelligent label and uses thereof, method for preparing solutions in ampoules, solutions and compositions based on conjugated polymers, and electronic device for monitoring radiation doses

A method is described for producing an intelligent label and solutions in ampoules, besides compositions based on conjugated polymers for monitoring radiation doses, the label and solutions, in an organic solvent, of (i) an electronic polymer (1-2000 μg/mL) and at least one organic crystal, inorganic crystal or luminescent dye (1-2000 μg/mL), or (ii) a combination of electronic polymers (1-2000 μg/mL), with solutions of said luminescent materials. The film-like label is obtained by drying solutions of luminescent materials on glass plates. The preferred materials are poly(2-methoxy,5-ethyl(2-hexyloxy)-p-phenylenevinylene) (MEH-PPV) as the preferred polymer and [aluminium-tris(8-hydroxyquinoline)] (Alq3) as the preferred organic crystal, besides various organic and inorganic dyes. The label and solutions in ampoules have a large variety of uses, as dosimetres of both ionising and non-ionising radiation, with therapeutic and technological aims, such as foodstuff irradiation in order to delay the ripening process.
