Study on the Optical Properties of High Refractive Index TeO2-PbO-ZnO-BaF2 Glass System

Abstract

The tellurite 60TeO2-20PbO-(20-x)ZnO-xBaF2 (x = 1, 3, 5, 6, 7, 9, and 11) series glass samples were prepared. The samples’ SEM, XRD, DSC, density, refractive index, and absorption spectra were tested. A self-made optical platform was used to measure and calibrate the refractive index. The relationship between glass composition and crystallinity was discussed. The effects of density, molar refractive index, and metal standard value on the refractive index of glass samples were studied. The results showed that TPZBF glass has a high refractive index, and the refractive index increases with the increase in BaF2 content.

Faraday Angle and Accuracy Measurement of Magneto-Optic Current Transmission Based on New Telluride Glass

“…So TPZBF glass was fabricated using a melting-quenching method at 1000°C and annealed at 250°C for 10 hours. A detailed composition and properties related to this glass are available in reference [7]. As showed in Table I.…”

“…So, the Faraday rotation angle β in the magnetic field can be defined as: So, the Faraday rotation angle β can be figured out through (7) to (10) in the experiment.…”

“…In the prototype based on the light reflection, using (1), (7), and (10), when the applied current I=220A, the Faraday angular is 32 degree; this increased rotation angle is attributed to the increase of light passing through the length of the glass and the polarised light that is rotated twice in the same TPZBF glass. 5 > yinsy@ncut.edu.cn < This design's sensitivity is the two values are very close to each other, which proved that the constructed system is accurate.…”

“…In this study, a high Verdet constant TeO2-PbO-ZnO-BaF2 (TPZBF) glass as a sensing head was designed and fabricated [7]. A low-cost, self-made, single-light-way measurement was set up, avoiding using a lock-in amplifier or uncertainties due 2 > yinsy@ncut.edu.cn < to variations in the optical path or light fluctuation from AC methods, significantly reduce the complexity and total cost [8].…”

Study on Radiation Shielding Properties of New Barium-Doped Zinc Tellurite Glass

“…For optical components, the higher the refractive index, the thinner the material can become, and the smaller the volume of the entire optical system. In some special working environments, such as space operations and medical equipment requiring radiation shielding ability and small instrument volume, the advantages of high refractive index glass are apparent [ 12 , 13 , 14 , 15 , 16 , 17 ]. Zinc oxide is added to the glass composition to ensure that the glass has a good structure and thermal stability [ 18 , 19 ].…”
