Abstract

This research focuses on investigating the features of spray-pyrolyzed antimony oxide, Sb₂O₃ nanomaterials synthesized at molar concentrations of 0.1 M, 0.2 M, 0.3 M, 0.4 M, and 0.5 M. The structural, morphological, elemental, optical, vibration modes, and electrical properties of the films were studied using the respective characterization equipment. X-ray diffractometry (XRD) plots showed a cubic crystal structure with stretchy-like morphology. The elements making up the deposited samples were investigated using energy dispersive X-ray spectroscopy (EDX) spectra. The samples recorded high absorbance features and optical conductivity values that increased at increasing molar concentrations. As the concentration increased, the band gap energies increased from 4.02 eV to 4.09 eV. The Urbach energies also showed slight increase in values from 3.93 eV to 3.97 eV with concentration. The Fourier transform infrared spectroscopy (FTIR) spectra showed the vibration modes and bonds existing between the synthesized compounds. The electrical result revealed increasing film thicknesses with molar concentration. The results show the potential application of the synthesized antimony oxide films in solar cell devices and optical materials.

研究喷雾热解法合成的氧化锑 Sb2O3 纳米材料的光学特性

本研究重点研究了摩尔浓度分别为 0.1 M、0.2 M、0.3 M、0.4 M 和 0.5 M 时合成的喷雾热解氧化锑（Sb2O3）纳米材料的特性，并使用相应的表征设备研究了薄膜的结构、形态、元素、光学、振动模式和电学特性。X 射线衍射（XRD）图显示了立方晶体结构和拉伸状形态。利用能量色散 X 射线光谱（EDX）对沉积样品中的元素进行了研究。样品记录了高吸光特征和光导率值，并且随着摩尔浓度的增加而增加。随着浓度的增加，带隙能从 4.02 eV 增加到 4.09 eV。随着浓度的增加，厄巴赫能量也从 3.93 eV 微升至 3.97 eV。傅立叶变换红外光谱（FTIR）显示了合成化合物之间存在的振动模式和化学键。电学结果显示，薄膜厚度随摩尔浓度的增加而增加。这些结果表明，合成的氧化锑薄膜具有在太阳能电池设备和光学材料中应用的潜力。
