Abstract

It was established that minimal content of the glass-forming component GeS2 is equal to 30 mol.% (by exploration the set of 23 different alloys with different composition). Correlation between structural properties, thermal parameters (glass transition, crystallization and melting temperatures) and optical absorption spectra along of the titled glasses system has been found. The temperatures, the band gap energy and the characteristic energy of vitreous alloys for the gastric system Tl2S‑In2S3‑GeS2 were investigated experimentally.

Highlights

Third-order non-linear optical materials are recently explored very intensively researched in the recent years due to the prospect of their use in ultra-high speed switcher, triggers, light modulators, deflectors et. for optical communications [1,2,3,4]
We present the study of the glass formation for similar glass system Tl2S–In2S3–GeS2 together with the optical properties of the obtained glasses
Glass-formation region in the quasi-ternary system Tl2S–In2S3–GeS2 was investigated by X-ray phase analysis

Summary

Introduction

Third-order non-linear optical materials are recently explored very intensively researched in the recent years due to the prospect of their use in ultra-high speed switcher, triggers, light modulators, deflectors et. for optical communications [1,2,3,4]. For optical communications [1,2,3,4] These materials include chalcogenide glasses which have relatively high refractive indices, wide transparency spectral range, and high thermal and chemical resistance [4]. Generally chalcogenide glasses are isotropic, they may possess promising photoinduced [5], photonics [6] and nonlinear optical [7] properties. [2] the possibility of using the Tl2S–Ga2S3–GeS2 glasses as materials for effective photoinduced third harmonic generation described by fourth rank tensors. We present the study of the glass formation for similar glass system Tl2S–In2S3–GeS2 together with the optical properties of the obtained glasses. Glass formation in the quasi-ternary systems based on the In2S3–GeS2 side was studied in [2]
