ORGANIC PHOSPHOR-FUNCTIONALIZED NANOPARTICLES AND COMPOSITIONS COMPRISING THE SAME

This technology relates to nanoparticles that are particularly beneficial in optical systems. The nanoparticles include phosphor-functionalized particles with an inorganic nanoparticle core, surface polymer brushes in the form of long and short-chain polymers bonded to the inorganic nanoparticle core, and organic phosphors bonded to the inorganic nanoparticle core or the short-chain polymers. Applications for this technology include LEDs, lighting devices, fixtures, efficient light conversion materials, etc.

Nanofilled Polymeric Nanocomposites with Tunable Index of Refraction

This technology relates to nanofilled polymeric materials with a tunable refractive index without increased scattering or loss. The tunability allows the creation of hybrid nanocomposites that combine the advantages of organic polymers (low weight, flexibility, good impact resistance, and excellent processability) and inorganic materials (high refractive index, good chemical resistance and high thermal stability).

GELATIN NANOCOMPOSITES

For most types of gelatin-based imaging elements, surface abrasion and scratching results in reduction of image quality. Thus, processing the image and, later, casual handling of the image can easily mark or disfigure the image. There is, therefore, a need for an imaging element having improved scratch resistance over materials currently used.
