1. 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 ofgenerating 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.
