SMALL CORE/LARGE SHELL SEMICONDUCTOR NANOCRYSTALS FOR HIGH PERFORMANCE LUMINESCENT SOLAR CONCENTRATORS AND WAVELENGTH DOWNSHIFTING

摘要

An article of manufacture and method for making a luminescent solar concentrator or a wavelength shifting device. The article includes a light guide or optical medium with a luminescent material disposed therein or deposited on the surface. The luminescent material is formulated to absorb incoming radiation and wavelength shift that radiation to a larger wavelength for processing and use, and to minimize reabsorption of the shifted radiation by the luminescent material.
