  • Optical materials, optical components, and methods
    Patent number: 9905724
    Abstract: An optical material comprising quantum confined semiconductor nanoparticles, wherein at least a portion of the nanoparticles are in a charge neutral state is disclosed. Also disclosed is an optical component including an optical material comprising quantum confined semiconductor nanoparticles, wherein at least a portion of the nanoparticles are in a charge neutral state. Further disclosed is an optical material obtainable by at least partially encapsulating an optical material comprising quantum confined semiconductor nanoparticles and irradiating the at least partially encapsulated optical material with a light flux for a period of time sufficient to neutralize the charge on at least a portion of the nanoparticles.

  • OPTICAL MATERIALS, OPTICAL COMPONENTS, DEVICES, AND METHODS
    Publication number: 20170121602
    Abstract: An optical material comprising quantum confined semiconductor nanoparticles having an improved solid state photoluminescent efficiency is disclosed. Also disclosed is an optical component including an optical material comprising quantum confined semiconductor nanoparticles having an improved solid state photoluminescent efficiency. Further disclosed are methods for treating an optical material comprising quantum confined semiconductor nanoparticles. Further disclosed are methods for treating an optical component including an optical material comprising quantum confined semiconductor nanoparticles. One method comprises exposing the optical material to a light flux and heat for a period of time sufficient to increase the solid state photoluminescent quantum efficiency of the optical material by at least 10% of its pre-exposure solid state photoluminescent quantum efficiency value.
