Magneto-optical borogermanate glasses and fibers containing Tb³.

ABSTRACT: New glass compositions containing high concentrations of Tb³⁺ ions were developed aiming at the production of magneto-optical (MO) fibers. This work reports on the structural and MO properties of a new glass composition based on (100 - x)(41GeO₂-25B₂O₃-4Al₂O₃-10Na₂O-20BaO) - xTb₄O₇. Morphological analysis (HR-TEM) of the sample with the highest concentration of Tb³⁺ ions confirmed the homogeneous distribution of Tb³⁺ ions and the absence of nanoclusters. All the samples presented excellent thermal stability against crystallization (ΔT > 100 °C). An optical fiber was manufactured by a fiber drawing process. The UV-Vis spectra of the glasses showed Tb³⁺ electron
