摘要：Electrochemical light emitting devices are disclosed which include a compositematerial in contact with two electrodes. The composite material is an admixture of ionicspecies and an `immobile` semiconductor. The semiconductor is capable of supportingboth p- and n- type carriers and having a doping profile which can be dynamicallychanged in a controlled fashion through reversible electrochemical oxidation andreduction. Devices having this structure may be used to generate electrochemicallyinduced p-n junctions, thereby providing a new means of exploiting the light emittingproperties of such junctions under an applied voltage. Systems and methods forgenerating useful levels of light employing these devices are also disclosed.
