Abstract
The organic electroluminescent component of the invention has a transparent bottom electrode situated on a substrate; a top electrode composed of a metal that is inert to oxygen and moisture; at least one organic function layer arranged between the bottom electrode and the top electrode; and a charge carrier injection layer containing a complex metal salt of the composition (Me1)(Me2) Fm+n, whereby the following applies:m and n are respectively a whole number corresponding to the valence of the metals Me1 and Me2 (the metal Me1 thereby has the valence m, the metal Me2 the valence n),Me1 is selected from a group consisting of Li, Na, K, Mg and Ca,Me2 is selected from a group consisting of Mg, Al, Ca, Zn, Ag, Sb, Ba, Sm and Yb,with the prescription: Me1≠Me2.
