It is an effect of inhomogeneity of the sample, that is, the variation in
the metal density throughout the X-ray beam footprint.

Dear All,
I have monitored the growth process of YbVO4 nanoparticles using EXAFS. Here, nanoparticles were synthesized in water medium. Both initial and final products (EXAFS) of the synthesis were measured using the continuous flow approach whereas the intermediate products were recorded, in the glass capillary, using the stopped flow. In the attached figure, you can find the same (all products). At high energies of EXAFS, both initial and final measurements show smooth behavior whereas the oscillating pattern/bump was observed for the intermediate states.
Here, my question is: Is the oscillating pattern appearing in the intermediate states due to the sedimentation/in-homogeneity of the product in the capillary or it is the characteristic of the synthesis?
With regards, Raj _______________________________________________ Ifeffit mailing list Ifeffit@millenia.cars.aps.anl.gov http://millenia.cars.aps.anl.gov/mailman/listinfo/ifeffit Unsubscribe: http://millenia.cars.aps.anl.gov/mailman/options/ifeffit
