Abstract: Disclosed herein are luminescent nanoparticles comprising ln 1-x Zn x As and ln 1-y Zn y P, wherein x is from 0 to 0.5, y is from 0 to 0.6, and the molar ratio of ln 1-x Zn x As to In1-yZnyP is from 1:4 to 1:5000. In a preferred embodiment, the luminescent nanoparticles are lnAs-ln(Zn)P-ZnSe-ZnS quaternary giant-shell quantum dots that possess efficient photoluminescence in the near-infrared region with a large Stokes shift and minimal reabsorption. The core-shell nanoparticles may be particularly useful in the formation of a luminescent solar concentrator when used as part of a composite material formed from the nanoparticles and a suitable polymer. Also disclosed herein are methods to manufacture the nanoparticles, the composite materials and solar concentrators.
