Abstract
A security element for a security and/or valuable document includes a matrix based on an organic polymeric material and at least one electrically conductive pigment dispersed in the matrix and at least one organic luminescent substance dispersed in the matrix. In the presence of the conductive pigment the luminescent substance is capable of non-contact excitation of light emission where the particle size is less than 200 nm. The luminescent substance is not encapsulated and is directly surrounded by the matrix and is embedded therein.
