α‐SnF2: A UV Birefringent Material with Large Birefringence and Easy Crystal Growth

The simple binary fluoride α‐SnF2 is shown to be an excellent birefringent material with outstanding birefringence, about 14 times that of MgF2. Furthermore, it exhibits a shorter UV cutoff edge and easy crystal growth at ambient temperature compared to YVO4 and TiO2. A novel theoretical calculation...
