Green Synthesis of CuInS2/ZnS Nanocrystals with High Photoluminescence and Stability
Figure 5
XRD patterns of prepared samples with different Zn/Cu feeding molar ratios. Reference patterns of bulk zinc blend ZnS and chalcopyrite CIS are also shown at the top and bottom, respectively [30, 31]. CIS QDs were prepared at 240°C for 60 min; growth of ZnS was at 240°C for 180 min.
