“…Details of the preparation method can be found in our previous work. 20,21 The synthesized powders and hot-pressed Yb 3 Al 5 O 12 ceramic were identified by an XRD (D8 Advanced, Bruker, Germany) utilizing Cu K a radiation (k 5 1.54178 Å) with a step size of 0.02°at a scanning speed of 1°/min. The lattice parameters of Yb 3 Al 5 O 12 were refined by the Rietveld method (Topas software, Bruker, Germany).…”
