Abstract
Solid state lighting devices containing quantum dots dispersed in polymeric or silicone acrylates and deposited over a light source. Solid state lighting devices with different populations of quantum dots either dispersed in matrix materials or not are also provided. Also provided are solid state lighting devices with non-absorbing light scattering dielectric particles dispersed in a matrix material containing quantum dots and deposited over a light source. Methods of manufacturing solid state lighting devices containing quantum dots are also provided.
