Abstract
The invention relates to a method for identifying an object, wherein said object has a security element, which contains one or more inorganic luminescent pigments, wherein the method comprises the steps of producing an emission spectrum of the luminescent pigment and comparing the obtained emission spectrum with the spectrum specified for the security element. The invention further relates to a security element, by means of which it is possible to determine the authenticity of a product in a simple manner.
Claims18
Method for identifying an object, wherein the object comprises a security element which contains one or several inorganic luminescent pigments, whose emission spectrum/emission spectra change as a function of the energy of the exciting electromagnetic radiation, the temperature, the time after action of the excitation pulse or the ambient pressure, the method comprising the steps of
- generating at least 2 emission spectra of the luminescent pigment, wherein these spectra can be obtained with excitation pulses that are different from each other and/or as a function of the time, i.e., time intervals from action of the excitation pulse and/or change of the ambient pressure,
- comparing the obtained emission spectra with spectra predetermined for the luminescent pigment.
(canceled)
(canceled)
Security element with concealed or open security feature for its identification, which contains one or several inorganic luminescent pigments, wherein for each luminescent pigment at least one emission spectrum can be generated as a function of the spectral excitation energy, the temperature, the time after action of the excitation pulse or the ambient pressure, wherein at least two emission spectra different from each other are generated.
Device for identifying an object which comprises
- means for generating an excitation pulse,
- a detector for recording an emission spectrum.
