Abstract Lithium (0, 1, 3, 5%) doped Ba0.55Sr0.45TiO3 (BLST) thin films have been successfully manufactured by growing Li2O-doped Ba0.55Sr0.45TiO3 on the surface of p-type Si (111) substrate. Concentration of 1 M with annealing temperature of 850 °C for 15 hours was used in BST and BLST films. The Li dopant addition induced smaller lattice paramater, film thickness, gap energy, and greater refractive index. These results were supported by imaging surface morphology which Li+ ion can replace Sr2+ ion in the structure due to its small radius. Characterization of BST and BLST films structural showed they have cubic structure.

摘要 通过在 p 型 Si (111) 衬底表面生长 Li2O 掺杂 Ba0.55Sr0.45TiO3 成功制备了锂 (0, 1, 3, 5%) 掺杂 Ba0.55Sr0.45TiO3 (BLST) 薄膜。在 BST 和 BLST 薄膜中使用 1 M 的浓度和 850 °C 的退火温度 15 小时。添加 Li 掺杂剂导致更小的晶格参数、薄膜厚度、间隙能量和更大的折射率。这些结果得到了成像表面形态的支持，Li+ 离子由于其半径小而可以取代结构中的 Sr2+ 离子。BST 和 BLST 薄膜结构的表征表明它们具有立方结构。
