Er3+ ions-doped germano-gallate oxyfluoride glass-ceramic containing BaF2 nanocrystals was prepared through conventional melt quenching and subsequent thermal treatment method. X-ray diffraction patterns and transmission electron microscope images confirmed the formation of BaF2 nanocrystals in glass-ceramics. Preferential incorporation of Er3+ ions into the BaF2 nanocrystals were confirmed by the absorption spectra and emission spectra, and enhanced upconversion emission and infrared emission were observed. Relatively high transmittance in the mid-infrared region indicated great potential of this germano-gallate oxyfluoride glass-ceramics as host materials for the efficient mid-infrared emission from rare-earth ions. © 2015 The American Ceramic Society.
