Abstract

Y<sub>2</sub>(Te<sub>4</sub>O<sub>10</sub>)(SO<sub>4</sub>), featuring a unique (Te<sub>4</sub>O<sub>10</sub>)<sup>4−</sup> polyanion, exhibits a large birefringence (0.124@1064), wide energy band gap (4.1 eV) and high thermal stability (&gt;700 °C), which make it a potential birefringent material.
