Abstract: The present invention relates to a light-emitting device including a light source, a first light-emitting material spaced apart from the light source, and at least one additional light-emitting material. The first light-emitting material includes low reabsorbing semiconductor nanocrystals having an emission-center core, an exterior protective shell, and at least one inner light-absorbing shell. The device is useful for efficiently producing white light having a high color rendering index.

Abstract: The present invention provides substantially monodisperse colloidal nanocrystals and new preparative methods for the synthesis of substantially monodisperse colloidal nanocrystals. These synthetic methods afford the ability to tune nanocrystal size and size distribution. By using non-coordinating solvents in the synthetic process, these procedures constitute easier, less expensive, safer, and more environmentally "green" methods than those currently in use. This invention is generally applicable to any II-VI or III-V semiconductor material, and may be useful in generating metal-nonmetal compounds involving transition metals as well.
