Paper Abstract

Technology of tellurite glasses from the TeO2-WO3-PbO system rare earth doped has been investigated. This kind of materials possess high transparency in the visible and IR spectral range (up to 6&mgr;m) and low dispersion. Because of introduction of rare earth into glass structure, obtained materials possess very good properties such as: luminescence, high refractive index (higher than 2.0), which is a consequence of high polarizability of tellurium ions. Addition of lanthanum fluoride into glass structure from the TeO2-WO3-PbO system change the tendency to crystallization. The effects of the crystallization of glasses from the TeO2-WO3-PbO system LaF3 and other rare earths doped were a subject of the study. Differential thermal analysis, XRD, SEM measurements have been considered in term of rare earth influence. Particular interest present rare earth doped materials. This is caused by their relatively large radius compared to the other compounds as well due to specific luminescent properties of the rare earth ions. In the present work the data concerning the influence of the rare earth on the emission properties of glasses has been presented.
