I have the XPS spectrum of the Dysprosium element for both high energy and low energy regions. I would like to know if Dysprosium has an oxidation state of Dy2+. Is there any way to calculate the binding energy of different oxidation states of Dysprosium theoretically (except DFT method) so that I can distinguish it in my spectrum among other signals? Does Dy2+ even exist naturally? if yes, would you please recommend me some potential references with their XPS results in it?
There is a publication that claims to have found Dy2+ in doped endohedral fullerenes:
Article Crystal structure and electronic transport of Dy@ C_ {82}
Are you allowed to share your spectrum with us?
Well, via E-mail I can't say much more, that paper isn't mine, it's just one of the rare papers in which a Dy2+ species is reported.
If you don't want to show your spectrum publicly, you can also use a direct message here in RG.
Dear Hamed Salimkhani, Dy2+ does not occur naturally, as it is too strongly reducing. However, works by M. N. Bochkarev , Gerd Meyer and William J Evans have shown, that well-defined solid-state and molecular compounds of Dy2+ can be isolated.
Dear Hamed Salimkhani , for your information, please find below a representative paper of each of the three authors dealing with divalent dysprosium:
Article A New Route to Neodymium(II) and Dysprosium(II) Iodides
Article The First Ternary Iodides with Divalent Dysprosium
Article Large Scale Synthesis of Dysprosium and Neodymium Diiodides
Dear Hamed Salimkhani, you're very welcome. Please let me know if you need any further information.
