Dear Nilson,

It is simple!

Please check the following reference:

Materials Science and Engineering B 113 (2004) 121–124

Please use this protocol in your lab and check the results. If you don't get it then you can ask me and I will see if I can help you afterwards. Please also tell me which chemical precursors you will use. Just give it a shot.

Good luck!

Yurii Ivakin

Dear Nilson!

I can offer several variants of synthesis (in attach).

Yours sincerely
