Generally, the shift of the peaks in XRD can be attributed to:

1- The change of the d-spacing of the investigated system, this may attributed to many reasons including the effect of dopant, strain, surface (for nanomaterials

How the effect of the dopant and strain attributed to change of d spacing in the investigated system?

Please refer to any textbook on XRD, Elements of X-Ray Diffraction by Cullity, B. D is a good one.
