(MFG) for up-conversion luminescence was reported.X-ray diffraction spectra and Raman spectra of MFG vitroceramic were measured.The results confirm that there exist many cubic-BaF2 nanocrystals in MFG vitroceramic and the phonon energy of cubic-BaF

co-doped MFG samples were also measured.Several proofs on RE ions enriched nanocrystals were presented.In the end
we discussed the effects of nanocrystal-phase structure on red up-conversion luminescence.
