| الوصف: | In this study, we report ZnO and Bismuth-doped ZnO (rBi/Zn) (r = 3, 6, 9 wt%) nanoparticles through the hydrothermal synthesis method. Different characterization techniques such as XRD, TGA, FTIR, XPS, FESEM, EDX analysis, UV spectroscopy, and PL spectroscopy have been used to investigate the influence of Bi+3 doping over the synthesized rBi/Zn nanoparticles. XRD result reveals a reduction of average particle size from 30 to 21 nm with the increment of Bi+3 (3 → 9 wt%) concentration. The mass variation in rBi/Zn was found more than the pure ZnO sample which reveals in TGA results. The material rBi/Zn exhibits a single-stage to multi-stage decomposition with the enhancement of Bi+3 (3 → 9 wt%) concentration while the XPS result indicates that the reduction of binding energy with increasing Bi+3 doping. UV analysis shows that as the concentration of Bi+3 increases the band gap of the material rBi/Zn reduces from 3.217 to 2.901 eV. However, the conductivity analysis shows the enhancement in the conductivity of rBi/Zn (0 → 6 wt%) but decreases from 6 → 9 wt%. Furthermore, the morphology of rBi/Zn also changes as the doping of Bi+3 increases which is possibly due to the enhancement of lattice mismatch, and pH variation. Such a kind of rBi/Zn nanocomposite material could be used in optoelectronic devices or fiber optics-based gas-sensing applications. |
