- Аннотация: Near- and mid-infrared ranges have a huge potential for applications in photonics and electronics, and therefore the demand for materials that transmit radiation above 2 μm is growing. Glasses in the PbCl2-TeO2 system are promising materials for this purpose, since they have low phonon energies, a wide glass formation region and good resistant to crystallization [1]. In this study, we synthesized a series of glasses with the general formula of xPbCl2-(100-x)TeO2, where 10≤х≤50 mol %. By Raman spectroscopy it was found that the introduction of PbCl2 into the glass composition led to substitution units of TeO4 by TeO3 and depolymerization of the glass network. Structure transformation leads to significant changes in the physical properties of glasses: density, molar volume, glass transition temperature, refractive index and microhardness. The synthesized glasses have a wide transmittance range from 0.4 to 7.5 μm, chemical and thermal stability, and record low OH-group absorption. These makes the glass-forming system PbCl2-TeO2 promising for drawing optical fibers and application in laser systems.
