Abstract

The synthesis of Sn-doped Sb₂O₃ thin films using the spin coating method aims to investigate the effect of various Sn concentrations on the optical and structural properties, which has not been previously reported. FESEM revealed some hexagonal and cubic-shaped structures on the surfaces with thicknesses ranging from 6 to 13 μm. EDS confirmed successful Sn doping in the Sb₂O₃ lattice, and XRD patterns identified a cubic Sb₂O₃ phase for 0.1 M Sn and became to an amorphous nature for 0.2 M Sn. The structure transformed to orthorhombic from 0.3 to 0.5 M Sn. The structural properties show that the 0.3 M Sn doping exhibits minimal structural defects and disorder. In addition, the films exhibited almost 90 % transmittance in the visible region and dramatical reduction in the ultraviolet region. The 0.3 M Sn doping exhibited high absorption coefficients with the lowest Urbach energy and optimal bandgap. These findings highlight the need for high-quality optical thin films fabricated using the spin-coating method.

Sn浓度对自旋镀膜法氧化锑薄膜的影响：结构和光学性质分析

利用自旋镀膜法合成掺锡Sb2O3薄膜，旨在研究不同Sn浓度对其光学和结构性能的影响，这是以前没有报道过的。FESEM显示，在厚度为6 ~ 13 μm的表面上存在六角形和立方形结构。EDS证实Sn在Sb2O3晶格中成功掺杂，XRD图谱表明，当Sn为0.1 M时Sb2O3为立方相，当Sn为0.2 M时Sb2O3为非晶相。从0.3 ~ 0.5 M Sn转变为正交结构。结构性能表明，0.3 M Sn掺杂具有最小的结构缺陷和无序性。此外，薄膜在可见光区的透过率接近90%，而在紫外线区的透过率则显著降低。0.3 M Sn掺杂具有较高的吸收系数、最低的乌尔巴赫能和最佳的带隙。这些发现强调了使用自旋镀膜方法制备高质量光学薄膜的必要性。
