like wise how we use UV-Visible spectra that we can see the changes in absorbance b/w two same compounds, same way can we use XRD to differentiate b/w metal oxide and same metal oxide nanoparticle?
Thank for the reply.
i mean one is metal oxide and another one is same metal oxide but in nanoparticle form. is there any change we can see or same pattern will get in XRD.
The physical properties of materials at raw/bulk materials may differ at nano size of the same materials. Therefore, XRD patterns of the nanomaterials would show rather a different pattern than the usual pattern. The XRD peaks of nanoparticles are broader than the peaks of the same raw material. In X-ray physics, the crystallite size is inversely proportional to the FWHM of the diffraction peak (Scherer's formula), hence small particles or crystallites generally produces broader peaks. Moreover, you may find low diffraction intensity for nanoparticles compared to the raw/bulk material.
