Estudos das propriedades ópticas e estruturais dos vidros borosilicatos dopados com érbio e prata

Abstract

The borosilicate glasses are obtained from the combination of silicon dioxide (SiO2) with boron oxide (B2O3). Where these glasses have a wide range of applications in the glass industry, the sectors of going this laboratory equipment to the creation of optical (fiber optics). Because, due to its structural form these glasses have a large thermal shock resistance, good chemical durability and excellent electrical resistivity compared with other glasses on the market today. Therefore based on these important structural features, physical, chemical, and also in the variety of applications in this study was chosen for synthesis and characterization of pure borosilicate glass and doped with rare earth ions erbium and silver nitrate. In order to better understand the main properties of these glass matrices developed and how the ion emitters, or both metal nanoparticles behave when they are inserted in them, that , to prove that the insertion of dopants in borosilicate glass matrix changes both their optical and structural properties. We used the following characterization techniques: differential thermal analysis, density measurement, linear refractive index, optical absorption and transmission electron microscopy. Since the insertion of erbium ions in glassy materials has great potential for technological applications in the telecommunications, aiming to increase the capacity of data transmission. And the inclusion of silver nanoparticles nonlinear optical effect of third order in the composites and at wavelengths close to the characteristic surface plasmon resonance of the metal clusters. Thus, from the results and analysis obtained was possible to prove that the samples of borosilicate glass produced in this study showed satisfactory results that are similar to those found in the relevant literature, showing that this is a promising material for technological applications in the area of materials and optics.
