Optical, XPS and XRD Studies of Semiconducting Copper Sulfide Layers on a Polyamide Film
Figure 5
X-ray diffraction patterns of layers on PA 6 (peaks of djurleite—D, chalcocite—Ch). PA 6 initially pretreated for different time and then treated with Cu(I) salt solution for 20 minutes at . Pretreatment time: 1–4 hours, 2−5 hours.
