Abstract

Rare earth doped oxyfluoride glass-ceramics containing CaF2 nano-crystals were prepared by melt quenching. For the crystallized samples, scanning electron microscopy (SEM) and X-Ray diffraction (XRD) experiments indicated the existence of nano-crystals with the incorporation of Rare earth ions in the lattice among the oxide glassy matrix, which is important for obtaining desirable luminescent performance of glass-ceramics. Absorption spectra of the obtained oxyfluoride glass-ceramics were studied. Emission spectra of the obtained samples were also studied under different excitation wavelengths..
