Abstract
NIR UC emission was observed in heavy Mn<sup>2+</sup>-doped RbZnF<sub>3</sub>:Yb<sup>3+</sup>,Mn<sup>2+</sup> designed by the dopant-distribution prediction simulation. The GSA/ESA and GSA/ETU models of the super-exchange-coupled Yb<sup>3+</sup>–Mn<sup>2+</sup>–Mn<sup>2+</sup> trimer are proposed for the NIR UC emission.
