Hello.

You may be referring to lattice parameters, which are the parameters of a unit cell: the size of cell's axis (a, b, c) and the angles between these axis (alpha, beta, gamma).

Considering you have ZnO unit cell, the doping with different atoms probably will affect the size of the cell, because of the influence of a bigger or smaller atom. Rietveld Refinement is one of the methods we can apply to check the parameters, and I can help you with this.

Sincerely,

Calclute the width of a diffraction peak at half of its maximum intensity (FWHM) , crystallite size(using the Scherrer equation) , strain (using the Williamson-Hall equation ).

or you may be referring to lattice parameters, which are the parameters of a unit cell: the size of cell's axis (a, b, c) and the angles between these axis (alpha, beta, gamma).

These parameters collectively provide information about the crystal structure, crystallite size, strain, and crystallographic orientation of ZnO. Analyzing these parameters helps researchers understand the material's physical and mechanical properties .

From XRD data you can find

1. The type of the crystal structure of your material. ( SC or BCC or FCC or Mixed)

2. The space group.

3. The lattice parameters

4. FWHM

6. The number of planes present in the material.

7. The phase transition.

8. Which atom of ZnO is replaced by Cu, Co, N.

Etc.

Do Rietveld refinement.
