Editing Conductive polymer (section)

=== Electroluminescence ===
[[Electroluminescence]] is light emission stimulated by electric current. In organic compounds, electroluminescence has been known since the early 1950s, when Bernanose and coworkers first produced electroluminescence in crystalline thin films of acridine orange and quinacrine. In 1960, researchers at Dow Chemical developed AC-driven electroluminescent cells using doping. In some cases, similar [[light emission]] is observed when a [[voltage]] is applied to a thin layer of a conductive organic polymer film. While electroluminescence was originally mostly of academic interest, the increased conductivity of modern conductive polymers means enough power can be put through the device at low voltages to generate practical amounts of light. This property has led to the development of [[flat panel display]]s using [[organic LED]]s, [[Photovoltaic module|solar panel]]s, and optical [[amplifier]]s.
