@Yaseen Muhammad, it depends upon your preparation and post-preparation treatments of the specimen. But generally, it may not be uniform throughout the samples, and the reason for it most of the samples will be having defects in them, and oxygen vacancy is also one of the main defects.
Thanks for your answer sir, is the oxygen contents in our sample (CuTl-1223) is uniform?
Try to do XPS and from the XPS you can find the uniformity of Oxygen distribution in the specimen. Because oxygen will have different energy values with different elements and different valency metals also.
I can suggest you another experiment to check the Oxygen uniformity in the crystal. It is Secondary Ion Mass Spectrometry, using this technique one can find out the uniformity of oxygen from the surface to even about 1 micron depth of the crystals.
@Safia Saroukh it is not a forum for fun, be serious hereafter do not play like this.
@Dharmadoss Sornadurai, sir this is the question of reviewers, we cannot do more characterization of our sample.Please give me reasonable answer sir,
@Yaseen Muhammad from the molecular formula Cu_0.5 Tl_0.5 Ba_2 Ca_2 Cu_3 O_10-δ , the oxygen stoichiometry is given as 10- δ, which means some amount of oxygen deficiency is there. As per the empirical formula it should like A8_O_8, but here u have given it as A_8O10_ δ, which means excess oxygen is there and the excess oxygen may not be periodically present in the lattice site, that is why I said that the O may not be uniformly present in the crystal.
Thanks sir, Dharmadoss-Sornadurai, sir as O10-δ you mean that (δ) is varies that why the oxygen content is not uniform in the Crystal?
