“…1,2 Furthermore, the high photoluminescence (PL) quantum efficiency of high-quality NQDs at room temperature 3,4 is important for applications. [5][6][7][8][9] To date, wurtzite NQDs have been mostly investigated, with CdSe as the prototypical example, [10][11][12] since the PL wavelength of CdSe NQDs can be tuned across the visible wavelength region. Alternatively, zinc-blende (e.g., CdTe, CdS, ZnSe, and ZnS) and rock-salt (e.g., PbS and PbSe) NQDs have been fabricated, which have considerably enlarged the wavelength emission range.…”
