CuSn co-doped CdS (CdS:CuSn) QDs with different Cu(I) and Sn(IV) doping levels have been successfully synthesized by a simple one-pot procedure. It was found that doping ratio of Cu(I) and Sn(IV) in CdS QDs significantly affected the photoluminescence (PL) quantum yields (QYs), Stokes shifts and emission window of as-prepared QDs. Compared to single Cu doping, CuSn co-doping further significantly improved the PL QYs of as-prepared QDs (up to 24.6%). The CdS:CuSn QDs may be used as potential emitters in PL industry.
