Luminescence, Energy Transfer, and Upconversion Mechanisms of Y2O3 Nanomaterials Doped with Eu3+,Tb3+, Tm3+,Er3+, and Yb3+ Ions

Luminescence, energy transfer, and upconversion mechanisms of nanophosphors (Y2O3 : Eu3+, Tb3+, Y2O3 : Tm3+, Y2O3 : Er3+, Yb3+) both in particle and colloidal forms were studied. The structure, phase, and morphology of the nanopowders and nanocolloidal media were determined by high-resolution TEM an...
