ABSTRACT:
Color-tailored and white-light emitting polymer colloid-based OLEDs are disclosed. Devices include electroluminescent (EL) colloidal conductive polymer systems that can include EL dyes or other EL materials. Systems can sequester multiple EL components in different colloids in a single emissive layer of an EL device with little or no appreciable energy transfer between colloids. Devices can exhibit tailored emissions over a broad range of wavelengths through mixing of, e.g., red, green and blue PLED colloids. Disclosed methods including incorporation of one or more electroluminescent dyes into a semiconductive EL polymer colloid that can isolate the dyes and prevent energy transfer while retaining individual color emission.
