How to know whether dopant ions are occupying interstitial sites in the lattice OR, replacing the host cations from their lattice positions?

I have prepared Y2O3 nanoparticles doped with 3% Ag & 3% Tb (at. wt. %). Now, how can I know the locations of Ag+ & Y3+ ions in the doped Y2O3 crystal? Also how we can keep the charge balance in...

How to understand and draw electronic transitions among different energy levels of neighboring Tb3+ and Ag+ ions in Y2O3 host lattice?

Lets assume the dopant concentration as 3(at. wt.)% for each of Tb3+ & Ag+ ions. So the sample composition is Y(1.94)Tb(0.03)Ag(0.03)O(3).

Is it necessary that all the XRD peaks of constituent compounds should appear in the XRD of Composite sample?

I have prepared nanocomposites of alpha Fe2O3 & ZnO. In XRD patterns of the composite sample, a dominant peak corresponding to [104] plane of alpha Fe2O3 is absent. However, other dominant...
