Special glasses based on TeO.sub.2./sub. and Pb.sup.2+./sup. systems:preparation and characterisation
Pedlíková, Jitka ; Ležal, Dmitrij ; Zavadil, Jiří
Samples of heavy metal oxide glass system of /TeO.sub.2./sub./.sub.60./sub. . /PbCl.sub.2./sub./.sub.40-x./sub. . /PbF.sub.2./sub..sub.x./sub. where x falls in <0;40>, were prepared and characterised by absorption and photoluminescence spectroscopy. The role of F to Cl subtitution on optical and luminescence properties has been investigated. Selected samples were doped by Er using metal, chloride and oxide precursors. Photoluminescence spectra have been measured in wide temperature range /4-300 K/.

Kalužný, J. ; Ležal, Dimitrij ; Kubliha, M. ; Mariani, E. ; Kozík, T. ; Pedlíková, Jitka ; Kostka, Petr
The contribution reports about the closed relation between the structural order of the special glasses and their electrical and optical properties.
Special Glasses Based on TeO2 and Pb(2+) Systems:Preparation and Characterisation
Pedlíková, Jitka ; Ležal, Dimitrij ; Zavadil, Jiří
Absorption, light scattering and lon-temperature photoluminiscence have been found for TeO2-Pb(2+) glass systems.
Reflectivity spectra of (PbO)X-(TeO2)1-x glasses
Navrátil, Jiří ; Ležal, Dimitrij ; Pedlíková, Jitka ; Horák, Jaromír
PbO-riched (PbO)x(TeO2)1-x glesses were measured in IR-region(100-1400cm-1). Found bands were assigned to specified vibratiions.
