Bottom-Emitting Large-Area Stacked White OLED with Silver Nanowires Network as Transparent Anode

摘要

We have demonstrated bottom-emitting large-area white OLED devices in which the transparent anode was formed by a random network of silver nanowires. This nanowire layer was deposited on the glass substrate from an aqueous suspension by spin-coating where it formed an optically and electrically uniform layer. The nanowire density of the film could be easily varied by a change in coating process parameters which resulted in sheet resistances of the film between 5 Ω/sq and 10 Ω/sq.
