Abstract
This invention relates to a photoluminescent layer in the optical and adjoining spectral regions based on a solid solution of organic dyes. The photoluminescent layer consists of organic dye molecules with a low dye concentration and a matrix material of metal oxides, with the matrix material having a slightly sub-stoichiometric oxygen content. A method and a device for producing the photoluminescent layer are described.
