Abstract: The invention relates to a method for identifying pledged property, comprising the steps of: providing an apparatus, comprising: a guide tube in a substantially erect position, comprising an inlet and an outlet; and means for analysing the dynamic luminescence behaviour of a luminescent substance; wherein the means for analysing the dynamic luminescence behaviour of the luminescent substance are disposed so as to analyse the dynamic luminescence behaviour of the luminescent substance in the guide tube, even if said luminescent substance is in motion; introducing a pledged property containing the luminescent substance into the guide tube through the inlet; analysing the dynamic luminescence behaviour of the luminescent substance contained in the pledged property using the means for analysing the dynamic luminescence behaviour of the luminescent substance; and classifying the pledged property according to the result of the analysis.

Abstract: The present invention relates to a method of identifying and/or distinguishing materials by means of luminescence, wherein at least one luminescent substance is incorporated into the material and/or applied onto the material and the luminescence behaviour of the substance is analysed after excitation by means of radiation, and the use thereof for identifying and/or sorting and/or recycling and/or authenticating and/or performing a quality check and/or formulation check on materials.
