Disputed Mechanism for NIR-to-Red Upconversion Luminescence in NaYF4:Yb(3+),Er(3+)

The most commonly proposed mechanisms for NIR-to-red upconversion in the well-studied material β-NaYF4:Er(3+),Yb(3+) are evaluated in order to resolve inconsistencies that persist in the literature. Each of four possible mechanisms is evaluated in terms of the direct analysis of spectroscopic data....
