Copper (Cu) doped II–VI semiconductor quantum dots (QDs) manifest high luminescent dopant emission with excellent tunability.
Cu and In co-doped CdS QDs are synthesized and exhibit large Stokes shifts and tunable emission from green to near-infrared.
Highly efficient large-area luminescent solar concentrators (LSCs) were demonstrated using colloidal C-dots. The large-area LSC (225 cm2) exhibited an external optical efficiency of 2.2% (under natural sun irradiation, 60 mW cm−2).
