Optimization of Synthesis Conditions for Complex Se/Te Based Glasses*

Selenium and Tellurium-based glasses boast a high refractive index and a wide range of transmission in the infrared region of electromagnetic spectrum, making them ideal for applications such as lenses, optical fibers, and optical circuits. In this work, synthesis conditions of complex Bi-Ga-Ge-Se-Te glasses were investigated and optimized by varying melting temperature, quenching rate, and annealing process. The purpose was not only to create samples of new compositions, but also to refine the process for manufacturing quality samples for further practical applications. As a result, a number of high optical quality samples with different Bi content were successfully prepared and characterized with different experimental techniques.
