Why the position of the XRD peak of CdS changes when I use Ni anode instead of Cu?

03 March 2019 1 572 Report

XRD

Please refer to the Bragg equation:

lamda=2*d*sin(theta).

When changing lambda (= wave length of K-alpha radiation of the x-ray anode) from Cu K-alpha (~1,54A) to Ni K-alpha (~1,66A) you willl experience a theta shift (increase of theta) in order to fullfill the above equation. The lattice plane distances d of CdS will not be changed when changing the x-ray wave length.
