... morphology of CdSe NCs and CdSe/ZnS NCs with an average diameter of 2.4 and 3.6 nm, respectively. As a result, the best QY of PL was achieved for thickness of ZnS as two monolayers. The definition of ... narrow FWHM of PL (29–36 nm). The overcoating of CdSe NCs with ZnS usually results in small red shift of PL peak. To achieve CdSe/ZnS NCs with pure green luminescence, th...
