Annotation	HfO2/alpha-Al2O3 eutectics were grown by the micro-pulling down (mu-PD) method at the composition of 63.2 mol.% alpha-Al2O3, 35.512 mol.% HfO2, 0.92 mol.% Eu2O3 and 0.368 mol.% Y2O3. Rod phases with around 3-4 mu m diameter were observed on the transverse cross-section. The phase-separated scintillator fibers (PSSFs) structure with fibers of around 3-4 mu m diameter and 10-20 mu m length was observed. The electron back scattering patterns indicated crystal orientation of [101] for monoclinic HfO2 rod phase and [0001] for a-Al2O3 matrix in the transverse cross-section. Eu3+ 4f-4f emission was observed at 550-750 nm.
