Recent advancement in metal containing multicomponent chalcogenide glasses

Abstract

Amorphous semiconductors or chalcogenide glasses are the key materials in modern optoelectronics to make comfortable life of our society. Understanding of physical properties (like microstructure, thermal, optical, electrical) of these materials is important for their different uses. Predominant study of physical properties of the metal containing multicomponent chalcogenide glasses have attracted much attention, due to their interesting variable features and wide range of structural network modifications. Structural modifications in these materials are usually described with respect to the values of structural units (or average coordination number). In significance to this, the present work demonstrates the chronological development in the field of chalcogenide glasses along with scanning electron microscopy (SEM) morphologies. Optical, electrical and thermal correlative properties of recent developed Se93−xZn2Te5Inx (0 ≤ x ≤ 10) metallic multicomponent chalcogenide glasses are discussed. Variation in SEM morphology, refractive index (n), extinction coefficient (K), optical energy band gap (Eg), electrical conductivity (σav), crystallization activation energy (Ec) and glass forming ability (GFA) with structural units of Se-Zn-Te-In glasses have been demonstrated in this study. Subjected materials thermal, optical and electrical parameters have been achieved higher and lower in a respective manner at the threshold structural unit value 〈r〉.

A Comparative Analysis of Standard and Nano-Structured Glass for Enhancing Heat Transfer and Reducing Energy Consumption Using Metal and Oxide Nanoparticles: A Review

“…Modern technological applications of glass in diverse fields such as engineering, medicine, energy, communication and medicine, and communications are crucially dependent on our appreciation and awareness of the intrinsic connections between glass and nanotechnology [37][38][39][40][41]. Understanding the realistic mechanism of glass fabrication at the nanoscale size has recently been proved and a huge number of nano-materials applications have widely been studied and investigated, especially in mechanical engineering, i.e., the thermal and optical distinct properties of glass treated at the nanoscale size [42][43][44][45][46][47][48]. This has led literally to insight into the thermal and optical properties of the glass structure, band and micro-crack theories, surface modification, and controlled crystallization [49][50][51][52][53][54][55][56].…”

“…High refractive index and optical dispersion help them for superior optical properties. Due to their size and enhanced surface are they can be used as the catalysis for energy application to increases the functionality of any application [45]. Hanna kim et al [98] utilizes polymer nanofiber technology to improve the radiative passive cooling.…”

Optical properties of Se–Te–Sb thin films

“…Therefore they are excellent materials to be used in optical and photonic applications [2][3][4][5][6]. On the other hand, one of the most important properties of some chalcogenide systems is their rapid reversible phase transition between crystalline and amorphous states.…”

Spectroscopic properties of the Pr3+ ion in TeO2-WO3-PbO-La2O3 and TeO2-WO3-PbO-Lu2O3 glasses

“…Among trivalent RE ions, the luminescence features of the Pr 3+ ion have became more popular because of its specific 4f 2 configuration, possessing 91 degenerate energy levels [9,10]. The tellurite glass systems doped with Pr 3+ ions have been widely studied for their structural details and luminescent properties [3,[11][12][13][14][15].…”
