Abstract (en)
[origin: CA2677418A1] The invention relates to a safety and/or valuable document having a safet y element, wherein the safety element has a photonic crystal arranged on a s ubstrate in relation to an orientation defined on a surface of the substrate , and a luminescent substance. It is characterized in that an emission wavel ength lambda of the luminescent substance, and a grid constant of the photon ic crystal are aligned with each other and specified according to the formul a lambda = m * 2 * d, wherein d is a distance between two lattice planes of the photonic crystal, and m is a positive integer.
