Abstract
A light emitting composite arrangement and related device includes an electroluminescent polymer material which emits ultraviolet light and a plurality of photoluminescent nanoparticles energetically coupled to the polymer. The arrangement and device emits red-shifted light relative to the ultraviolet light. Through use of different size nanoparticles, different colors can be provided, such as in pixelized form.
