合成了一种新的硼碲酸盐 LaTeBO5，含有高度扭曲的 [Te(iv)O4] 基团。有趣的是，它表现出较宽的紫外线透过率范围和较大的双折射（0.080@1064 nm）。响应电子分布各向异性近似和偶极矩计算表明，高度不对称的[Te(iv)O4]和BO3基团的协同效应有利于其大双折射。
A new borotellurite, LaTeBO5, containing the highly distorted [Te(iv)O4] group has been synthesized. Interestingly, it exhibits a wide ultraviolet transmittance range and large birefringence (0.080@1064 nm). The response electron distribution anisotropy approximation and dipole moment calculation demonstrate that the synergistic effect of the highly asymmetric [Te(iv)O4] and BO3 groups is conducive to its large birefringence.
