Theoretical study on the optical properties of Ge-doped bismuth silicate crystals
This article uses the first principles calculation method based on density functional theory to calculate and analyze the optical properties of BSO (B 4 Si 3 O 12 , BSO) crystals doped with different ratios of Ge. When the doping ratio of Ge is 1/12 and 1/6, the BGSO mixed crystal system has better polarization response-ability, the dielectric constant increases, the charge binding ability is enhanced, and the dielectric loss is reduced. When the proportion of Ge doping increases to 1/3, the optical properties of BGSO mixed crystals significantly deteriorate, indicating that an appropriate amount of Ge-doped BSO crystals can improve their polarization ability and reduce dielectric loss, effectively improving their optical properties.
