Abstract

There is a pressing demand for the development of novel birefringent crystals tailored for compact optical components,especially for crystals exhibiting large birefringence across a range of temperatures.This has commonly been achieved by introducing various deformable groups with high polarizability anisotropy.In this study,we combined both rigid and deformable groups to synthesise a new birefringent crystal,Al2Te2MoO10,which demonstrates an exceptional birefringence value of 0.29@550 nm at room temper-ature.Not only is this higher birefringence than that of commercial crystals,but Al2Te2MoO10 exhibits excellent birefringence stability over a wide temperature range,from 123 to 503 K.In addition,the first-principles theory calculations and structural analyses suggest that although the rigid AlO6 groups do not make much contribution to the prominent birefringence,they nonetheless played a role in main-taining the structural anisotropy at elevated temperatures.Based on these findings,this paper proposes a novel structural design strategy to complement conventional approaches for developing optimal birefrin-gent crystals under various environmental conditions.
