Structural and magneto-optical properties of PbO–Bi2O3–B2O3–Al(PO3)3 glasses
Source abstract
Abstract
Abstract Herein, diamagnetic PbO–Bi2O3–B2O3–Al(PO3)3 glasses are prepared by melt-casting and the influence of phosphorus tetrahedral on the structure and optical properties of the glass has been systematically investigated. Compared to diamagnetic PbO–Bi2O3–B2O3 (PBB) glasses, the original boron chain network has been replaced by the boron-phosphate structure. The metaphosphate forms [PO4] units and expands the glass network, which leads to the decline of density and the increase of refractive index (up to ~2.423 @633 nm). The improvement of the magneto-optical properties performs in that the Verdet constant achieves 0.203 min/G cm at 633 nm and higher magneto-optical figure of merit displays a better optical performance than the diamagnetic glass without metaphosphate.
