Abstract: Quantum dot (QD) LEDs useful for plant, algael and photosynthetic bacterial growth applications. The QD LEDs utilizes a solid state LED (typically emitting blue or UV light) as the primary light source and one or more QD elements as a secondary light source that down-converts the primary light. The emission profile of the QD LED can be tuned to correspond to the absorbance spectrum of one or more photosynthetic pigments of the organism.

Abstract: A light emitting layer including a plurality of light emitting particles embedded within a host matrix material. Each of said light emitting particles includes a population of semiconductor nanoparticles embedded within a polymeric encapsulation medium. A method of fabricating a light emitting layer comprising a plurality of light emitting particles embedded within a host matrix material, each of said light emitting particles comprising a population of semiconductor nanoparticles embedded within a polymeric encapsulation medium. The method comprises providing a dispersion containing said light emitting particles, depositing said dispersion to form a film, and processing said film to produce said light emitting layer.
