| Popis: | ZBLYALi core glasses modified by the substitution of LiF for BaF 2 or the addition of PbF 2 and cladding glasses of ZBLYAN composition, into which HfF 4 and NaF were substituted, are described and characterised by their thermal glass parameters and refractive index changes. Glasses studied, with T g range from 533 to 573 K, yielded numerical apertures as high as 0.39, if ZBLYALiPb glasses were used as core. Since incorporation of PbF 2 in ZBLYALi glass led to a strong decrease in glass stability, a closer look at the crystallisation behaviour of ZBLYALiPb was taken. Addition of PbF 2 was found to suppress precipitation of LiBaZr 2 F 11 in favour of a (Ba, Pb)ZrF 6 solid solution with orthorhombic structure. |
