I have coated Copper on fabrics by RF sputtering method. The XRD result shows that fabrics peaks along with Cu(111) peak.
Dear Vinisha
please use x-ray imaging (you need 2-D capability) technique(s) in order to see whether your Cu coverage on your fabrics is homogenous or inhomogenous or even has got discontinuities; but not with XRD. That is a technique for structural analysis of the sample's crystal lattice, but not on its mass coverage.
....but I may have misunderstood your question....
Powder XRD is an integral technique. You get a number (counts) for a certain sample/detector rotation. There is no information in this data set which enables you to make any conclusion about the position where the signal is coming from. If you could scan the sample and investigate the change in X-ray intensity ... this would work. This is practically the technique used in Scanning Electron Microscopy. There instead of X-rays electrons are used. However, electrons also generate x-rays (as in your x-ray tube) so that collected x-ray counts would allow this as well. But the resolution compared to electrons is worse so that electron images are preferred compared to x-ray maps. X-ray element distribution maps have other applications...but it is very close to that one you want do. However, if your coating is bigger than the information depth you cannot do this with EDX of course.
Dear Gerhard Sir,
Thank you so much for your answer. The EDS and elemental mapping show the Cu particles are homogeneously speared on the fibers.only one peak related to copper Cu(111) is present in the XRD what about remaining peaks?
Why is only one peak related to copper Cu(111) present in XRD studies?
The reason is crystallographic texture! At least I guess so since you do not show any diffractogram so that I do not have any experimental confirmation. However, for sputtering a strong texture is not unexpected. A careful look would possibly also show some minor intensities form other interferences.
Preferred orientation / texture (as Gert mentioned) is the reason. The fabric itself via the fiber direction is an unisotropic support having preferred direction, which may be benificial for textured growth of your Cu coverage.
