摘要：

Erbium doped transparent glass-ceramics were obtained in the family (50GeO(2)[50-y]PbO, yPbF(2)+xErF(3)). With controlled crystallisation of glasses by inhomogeneous nucleation and growth during reheating, PbF2 crystallites of nanometric size and a filling factor of 10(-2) were obtained. The phase separation process was studied by thermal analysis, X-ray diffraction and Transmission Electron Microscopy as a function of the precursor glass composition and thermal treatments. The Raman spectra were also measured. (C) 2000 Kluwer Academic Publishers.
