From BaAlBO3F2 to BaAlB3O6F2 and BaAl2(B3O6)2F2: the Enhancement of Birefringence and Band Gap by Extending the π-Conjugated System Combined with [Al-O/F] Functional Groups The investigation of birefringent materials is predominantly focused on π-conjugated system, however, the large band gap or deep ultraviolet (DUV) transmittance cannot be guaranteed. In this work, we proposed an extending π-conjugated strategy to increase the birefringence while keeping the large band gap.
