A valuable document comprising at least one security element that is provided with a marking layer in a marking region, the layer containing an electroluminescent pigment and being applied to a carrier body. The electroluminescence of the pigment of one such valuable document must be able to be excited even with comparably low, externally applied field intensities. To this end, a plurality of electrically insulated field displacement elements having a minimum dielectric constant of 100 are distributed over the surface of the marking region, the field displacement elements being at a distance of approximately between 5 &#x3bc;m to 500 &#x3bc;m from each other and compressing the applied field in the gaps thereinbetween.

Valuable document comprising a security element and method for producing said valuable document

An apparatus configured to discriminate the genuineness of a certified paper by exposing the paper to a light source and transporting the paper through an environment of an alternating-current electromagnetic field. Light detectors detect the light reflected from the paper and the light emitted by a fluorescent ink on the paper and output a waveform corresponding to the intensity of the detected light, reflected light, and the detected emitted light as the paper is scanned. The resulting waveforms are used to discriminate the genuineness of the paper. The fluorescent light and reflected light can be optically split and directed to separate detecting devices. Furthermore, the alternating-current electromagnetic field can be controlled by a voltage controller and configured to be driven only when the sensor detects light from the fluorescent ink.

Certified paper discriminating apparatus

An apparatus for discriminating the genuineness of a security mark is provided having a first light detecting element for detecting a light emitted from a luminescent ink of the security mark placed in a specified environment and a second light detecting element for detecting a reflected light from a non-luminescent ink of the security mark. The first and second light detecting elements detect the light from the same location of a bank note. A third light detecting element detects the light intensity of a light emitted from a monitor mark that can be compared with a preset reference light intensity to calculate a deviation from the reference light intensity. The output of the first light detecting element can be converted into a corrected output value corresponding to the calculated deviation. The genuineness of the bank note can be discriminated based on the corrected output value.

Certified paper and an apparatus for discriminating the genuineness thereof

A method and apparatus are disclosed for determining the authenticity of secured documents which include an authentication element of the type which, when excited with radiation of a specific excitation wavelength, emits radiation which can be detected by a detection unit and evaluated by an evaluating unit. The intensity profile of the emitted radiation is determined in a specified wavelength range over a predetermined measuring period after excitation and analyzed to determine authenticity of the secured document.

The present invention provides a secured document including a composition capable of anti-Stokes fluorescence containing an ion capable of absorption of electromagnetic radiation, an ion capable of emitting electromagnetic radiation, and a matrix composition comprising gadolinium, yttrium, lanthanum, and lutetium, wherein the wavelength of the emitted electromagnetic radiation is shorter than the wavelength of the absorbed electromagnetic radiation, and wherein the concentrations of the absorbing and emitting ions are adjusted to achieve concentration quenching of anti-Stokes luminescence.

Anti-stokes fluorescent compositions and methods of use

A manually controlled sensor for authenticity identification of luminescent identification features on documents is described, in which the identification feature is illuminated with an excitation wavelength and may respond at a different wavelength, with the response wavelength being detected and evaluated by a radiation receiver. In order to improve the sensitivity and to comply with the safety at work regulations, a focused beam ( ), which is emitted from a beam source ( ), is converted by focusing optics ( ) in such a manner that a scanning bar ( ), which is approximately in the form of a line, is projected on the surface of the object ( ) to be investigated, which causes the identification region ( ) which is arranged on the object ( ) to fluoresce in a luminescent manner in at least one subregion, and the luminescence signal produced in this way is passed via detection optics ( ) to an evaluation unit ( ), which evaluates the luminescence signal. The sensor is intended to be classified in laser class A.
