Sol–gel synthesis of Sr 1−x Yb x F 2+x nanoparticles dispersible in acrylates
A new approach to prepare nanoparticles in SrF 2 -YbF 3 systems via the fluorolytic sol–gel synthesis is presented. A series of Sr 1−x Yb x F 2+x (0.12 < x < 0.62) nanoparticles of nonstoichiometric fluorite phases obeying Vegard's law throughout the homogeneity area have been successfull...

For all Yb concentrations XRD patterns show the formation of cubic phases. For higher Yb concentration (>50 mol%) crystallite sizes decrease abruptly in comparison to lower Yb concentrations ( |
