<p>Producing an electrode comprises applying a dispersion comprising 50 wt.% particles smaller than 50 nm to a substrate and allowing the dispersion to solidify to form a first layer (3); and applying organic hole-injecting material(s) to the first layer to form a second layer. The dispersion comprises polymeric anion(s) and polythiophene(s). Producing an electrode comprises applying a dispersion comprising 50 wt.% particles smaller than 50 nm to a substrate and allowing the dispersion to solidify to form a first layer; and applying organic hole-injecting material(s) to the first layer to form a second layer. The dispersion comprises polymeric anion(s) and polythiophene(s) having repeating units of formula (I). A : optionally substituted 1-5C alkylene; R : OH, linear or branched, optionally substituted 1-18C alkyl, or optionally substituted 5-12C cycloalkyl, 6-14C aryl, 7-18C aralkyl or 1-4C hydroxyalkyl; and x : 0-8. Independent claims are included for: (1) a dispersion comprising polymeric anion(s), solvent(s) and polythiophene(s) having repeating units of formula (I); and (2) an electroluminescent arrangement comprising >=2 electrodes; and an electro-optically active layer between the electrodes.
