Key Points

To investigate the effects of fluoride ions on the birefringence and band gap of tin iodates.
Synthesis of Ba[Sn(IO3)6] and Ba[Sn(IO3)4F2] materials.
Characterization of optical properties, including birefringence and band gap measurement.
Comparative analysis of the effects of fluoride ions on material properties.
Ba[Sn(IO3)4F2] shows significantly enhanced birefringence compared to Ba[Sn(IO3)6].
The band gap of the fluoride-substituted material is notably larger than that of the non-fluoride material.
These findings indicate potential for improved performance in optical applications.

Implication

Novel materials demonstrate enhanced birefringence and band gap in optical devices, suggesting practical applications.

Abstract

Birefringent materials have garnered extensive attention as indispensable components in optical devices, including waveplates, polarizers, and optical isolators. In this study, two novel tin iodates birefringence materials, Ba[Sn(IO 3 ) 6 ] and Ba[Sn(IO 3 ) 4 F 2 ],...
