Abstract

Chalcogenide glasses form very wide family of non–oxide glasses which contain chalcogenide elements in combination with selected elements from III, IV, V, VI group of periodic system. These glasses opposite to SiO2 ones exhibit transmission in middle and far infrared region of spectra, higher values of refraction index and thus are very promising materials for drawing active and passive optical fibers for use in medicine and sensing. There are very important demands on preparation of base glasses in high chemical and physical purity and on detailed diagnostic measurements of their properties. Physical properties of these glassy systems are strongly influenced by the presence of structural units and chemical bonds and by the presence of one or more glass forming region. The attention in this paper is focused on the preparation of high purity base glasses, their doping with rare earth elements, and on optical and fluorescence measurements, X-ray analysis and fiber drawing..
