Abstract:The aim of this paper, study the effect of zinc oxide on optical properties of (PVA-PEG-ZnO) nanocomposites. The zinc oxide nanoparticle was added to the polymers maxture (polyvinyl alcohol 88wt.% and Polyethylene glycol 12wt.%) with different weight percentages are (0, 2, 4, 6) wt.%.. The optical properties were measured in the wavelength range (200-800) nm. The results show that the absorbance (A), absorption coefficient (α), extinction coefficient (k), refractive index (n) and real and imaginary dielectric constants (ε1 and ε2) of (PVA-PEG) blend are increasing with the increase of the weight percentages of zinc oxide nanoparticle. The energy gap (E g ) of (PVAPEG-ZnO) nanocomposites is decreased with the increase of the zinc oxide nanaparticles concentrations.

“…Instrument applications employing ChG generally request the glass to be processed into the forms of fibre or thin film. Traditionally, Ch-films are collected by physical vapour deposition (PVD) methods like thermal vaporization, pulsed laser deposition or sputtering from the bulk melt quenched ChG [139][140][141][142][143]. In general, when the laser deposition and sputtering matter they are largely restricted to 2-D surfaces and need high-vacuum processing and sometimes difficult target preparation.…”

Chalcogenide glasses, which are among the technologically very important materials, contain at least one chalcogen element as a major constituent and their utilization ranges from infrared (IR) optics applications to phase-change, optical-electrical data-recording. The interest to spectacle glasses exhibiting transparency in the IR region of the optical spectrum coincides with the mid-twentieth century. Firstly, heavy metal oxides were investigated and the transparency limit was extended from 3-5 μm (classical oxide glasses) to 7-8 μm wavelength. The widespread usage of infrared optics in the 20 th century has led to the need for new IR materials and to increase the IR transparency limit over 8 μm and scientists have tried chemical compositions of S, Se and Te in the 6 th group of the periodic table. Compared to oxide glasses, their mechanical strength and thermal stability are considerably lower and the calorimetric glasses form a new glass group with semiconductor properties. In this article, a brief overview of the definition, historical development, structure, properties and potential applications of chalcogenide glasses dating back to the early 1950s is given.
