    • The invention relates to a gonioluminescent security element (1) and to a method for producing such a security element, which is preferably embodied as a security document. The security element (1) comprises a first element (3) and a second element (5), which at least partly overlaps the first element (3), wherein the second element (5) faces an observation side (4) of the security element (1), wherein the first element (3) comprises first luminescence means and the second element (5) comprises at least one optical interference structure which has an orientation-dependent transmittance (11, 12) and/or reflectance (11, 12) in a distinguished wavelength range (14) wherein the first element (3) and the second element (5) are coordinated with one another in such a way that an optical change can be perceived in the case of observation during excitation of luminescence of the luminescence means depending on an orientation of the observation and/or a direction of incident radiation of excitation light through the second element (5), wherein the at least one interference structure changes its transmittance and/or reflectance in the distinguished wavelength range for precisely one orientation or in a delimited orientation range.
    • 本发明涉及一种安全goniolumineszentes元件(1)和用于生产这样的,其优选形成为安全文件的方法。 安全元件(1)包括第一部件(3)和第一元件(3)至少部分地重叠(5),其中,所述第二元件(5)的图面(4)的安全元件(1)面对,其中第二元件 所述第一元件(3)包括第一荧光粉和所述第二元件(5)包括至少一个光学干涉结构,其在一个优越的波长范围(14)定向相关的透射率(11,12)和/或反射率(11,12),其中 所述第一元件(3)和所述第二元件(5)被协调彼此,使得(荧光体的发光的激励期间观察时取决于进行观察和/或由第二元件5的激励光的照射的方向的取向 光学变化,可以感知到),其中所述至少一个干扰结构优良的波长范围内 具有精确一个方向或在分隔的取向范围其透射率和/或反射率的变化。
