Abstract

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.
