Need help for Tm (thulium)doped sample preparation



Hio everybody!
I have started my thesis focused on luminescence materials like Y2O3,
ZnO and other oxide doped Tm3+, but I lack doccument and knowledge, So
can somebody help me to know how to prepare these kinds of samples (in
nanoscale)? Thank you for reading this message,
