    • The invention relates to a security feature for protecting valuable documents, in particular for ensuring the authenticity of valuable documents. According to the invention, the security feature comprises a luminescent pigment which has a host lattice doped with a first luminophore and a second luminophore, with an excitation energy of the first luminophore being transferable to the second luminophore. However, in the case of the luminescent pigment according to the invention, the excitation energy is not transferred completely from the first luminophore to the second, but rather only partially. The incomplete transfer of the excitation energy is achieved by selecting suitable amount-of-substance fractions of the first and the second luminophores on the luminescent pigment. As a result of the incomplete transfer of the excitation energy, the luminescent light that is emitted by the luminescent pigment also has, in addition to a luminescence peak of the second luminophore, a luminescence peak of the first luminophore.
    • 本发明涉及用于保护有价文件的安全特征,特别是用于确保有价值的文件的真实性。 根据本发明,安全特征包括具有掺杂有第一发光团和第二发光团的主晶格的发光颜料,其中第一发光团的激发能量可转移到第二发光团。 然而,在根据本发明的发光颜料的情况下,激发能量不是从第一发光体完全转移到第二发光体,而是仅部分转移。 激发能量的不完全转移通过选择发光颜料上第一和第二发光体的合适的物质量分数来实现。 由于激发能的不完全转移,除了第二发光体的发光峰之外,由发光颜料发射的发光光还具有第一发光体的发光峰。
