Dubna University Scientists Discover New Properties of Telluride Glass

Scientists from Dubna State University, together with colleagues from Voronezh State Pedagogical University, have made an important advance in optics. They synthesized telluride glass based on tellurium, gallium, and germanium. It is used in complex devices.

Dubna University student Svetlana Badmaeva, under the supervision of FEIN Professor Dmitry Chareev, synthesized a sample of telluride glass based on tellurium, gallium, and germanium. This material is widely used in complex optical devices, and the new sample allowed them to draw two important conclusions.

First, they were able to confirm the universality of the equation, previously used only for metallic glasses: it has now been proven that it accurately describes the processes in telluride glasses as well. Second, the scientists discovered special local configurations—elastic dipoles—in the structure of the material. They influence the behavior of glass when heated and determine how energy is redistributed within it.

The resulting model will allow for more accurate calculations of the characteristics of telluride glasses, thereby improving the production technology of high-tech optics.

These glasses are used in space optics, laser devices, and electrochemical technologies. Understanding the fundamental mechanisms of aging and relaxation of the material will help more reliably predict its properties and optimize production processes.

The research results were published in the international journal Scripta Materialia.
