摘要

利用廉价的雾化器喷雾热解法制备了锌锑氧化物(ZnSb2O4)薄膜。X 射线衍射分析表明,ZnSb2O4 薄膜具有四方结构。结构指数分析表明,通过扩大 ZnSb2O4 层的厚度,ZnSb2O4 薄膜的晶粒尺寸增大,位错密度降低。此外,还利用 ZnSb2O4 薄膜的光学反射率 R 和透射率 T 来研究这些层的光学特性。对 ZnSb2O4 薄膜的光学研究表明,通过增加厚度,折射率值、乌尔巴赫能量和吸收系数都得到了改善。此外,这些薄膜的能隙分析表明,随着厚度的增加,它们的能隙从 3.75 eV 下降到 3.47 eV。对光电特性的研究包括通过增加厚度提高 ZnSb2O4 薄膜的光导率、电导率、光载流子浓度和光迁移率。研究人员推导了 ZnSb2O4 膜层的非线性光学指数,发现这些薄膜的非线性光学指数随着厚度的增加而提高。此外,通过热探针设备,ZnSb2O4 薄膜显示出 n 型半导体特性。

ZnSb2O4 Thin Films Synthesized by Nebulizer Spray Pyrolysis: Structural, Optical, and Optoelectrical Properties
Zinc antimony oxide (ZnSb2O4) thin films were prepared by inexpensive nebulizer spray pyrolysis. X-ray diffraction analysis showed that the ZnSb2O4 thin films have a tetragonal structure. The analysis of structural indices indicate that the grain size of the ZnSb2O4 films was enhanced by expanding the thickness of the ZnSb2O4 layers, and the dislocation density was decreased. Further, the optical reflectance, R, and transmittance, T, of the ZnSb2O4 sheets, were used to investigate the optical characteristics of these layers. The optical investigations of the ZnSb2O4 films refer to an improvement in the refractive index values, Urbach energy, and absorption coefficient by boosting the thickness. Moreover, the energy gap analysis of these films shows that their energy gap decreased from 3.75 to 3.47 eV as the thickness increased. The investigation of optoelectrical characteristics involves improving the optical conductivity, electrical conductivity, optical carrier concentration, and optical mobility of the ZnSb2O4 films by growing the thickness. The nonlinear optical indices of the ZnSb2O4 layers were deduced, and it was noted that the boost in the nonlinear optical indices of these films occurred by raising the thickness. Furthermore, the ZnSb2O4 films displayed n-type semiconducting properties by the hot probe equipment.
