“…In contrast to the wurtzite phased II-VI group QDs obtained by using other known cation exchange strategies, [5,17] zinc-blende phased II-VI QDs were preferred by applying the novel cation exchange strategy described herein. [24] In contrast, as shown in Figure 4C,i nt he as-prepared ZnS:Ag QDs here,the dominant and strongest room-temperature PL emission peak appears at 600 nm, without Svacancy induced emission. Most importantly,b enefitting from the thiol and solvent coordination, the controlled residual Ag + in deep positions could act as the effective doping in the resulting ZnS QDs matrix.…”
