Incorporation of CdFe2O4-SiO2 nanoparticles in SbPO4-ZnO-PbO glasses by melt-quenching process
(2018-01-01)
The development of glasses containing nanoparticles dispersed homogeneously with controlled size and optimum parameters for functionality is a big challenge. In the present work, the ternary system 60SbPO4-30ZnO-10PbO ...
Highly nonlinear Pb2P2O7-Nb2O5 glasses for optical fiber production
(2016-07-01)
In this study we present the production and characterization of Pb2P2O7-Nb2O5 glasses and optical fibers. The dependence of Nb2O5 content on thermal, structural and optical properties were investigated by thermal analysis ...

Phase separation in Ag–Ge–Se glasses
(Elsevier Science, 2007-05)
Field emission-scanning electron microscopy (FE-SEM) and electric force microscopy (EFM) measurements were carried out on bulk Agx(Ge0.25Se0.75)100−x glasses with x = 5 and 15 at.%. The presence of chemical contrasts and ...
Thermal and structural study of glasses in the binary system TeO2-Pb(PO3)(2)
(Elsevier B.V., 2013-11-01)
The main objective of this work has been to prepare and characterize the thermal and structural properties of glasses in the pseudo binary system TeO2-Pb(PO3)(2) with respect to the composition. Homogeneous and transparent ...
