Abstract
In this study, the SnO2 nanowires and Sb nanoparticles were synthesized using SnCl4.5H2O and SbCl3 by dissolving them in acetone. The solution was sprayed on a glass substrate via spray pyrolysis route. XRD patterns confirm a polycrystalline film with a tetragonal system. The FESEM analysis of morphology clarified a nanowire structure of SnO2 and nanoparticles structure of Sb. EDX proves that when Sb concentration increase, the SnO2 weight decrease from 72% to 68%. The optical properties have been well investigated by UV-VIS spectrophotometer, from this analysis, it can be observed that the absorbance, reflection, and extinction coefficient increased with the increasing of Sb content. The energy bandgap and refractive index elucidated a reduction with the augmentation of Sb content from 3.92 to 3.8 eV and from 2.24 to 2.22, respectively. The obtained characteristics make these films more suitable for nanoelectronics devices, this is due to their tunable controlling by their amount, and their nanostructures of nanoparticles stick on nanowires which render them more effective for the sensing devices.
