Dear Researchers,
I have my samples SnO2 doped with with Cu (1, 2, & 4%). The peak intensity reduces in XRD for 1 and 2%. However, for 4% additional peaks appears which I believe is due to increase in Cu content and possibly a change of phase. But the intensity of one of the peaks (200) shoots up for 4% doped sample in contrary to 1 & 2% where its intensity reduces. What can be possible explanation for the phenomenon?
Also, is there a possibility that SnO2 changed to SnO phase due to higher doping. If so, kindly share some reference papers.
Your expert advice is highly appreciated.
Hi, It is shifted to more 2thata... and the intensities may be increased or decreased depended on the amount of metal....
note the following manuscripts ..............
In my opinion the first step is to identify the additional phase (if any) which forms on progressive doping. Then you shoud compare its XRD data with reference XRD data
In XRD, the increase or decrease in intensity of the peak depends on the dopant. The variation in the intensity increases as well as decreases with different conditions. If there is any shift in the peak occurs means it is due to the difference in ionic radii of the metals. On the basis of ionic radii peak shifting can be observed.
