| Abstract: |
| : In this report, we have successfully synthesized ultrafine pure and Fe-doped SnO2 nanoparticles (NPs) by using a simple household microwave irradiation method. After the NPs were synthesized by microwave irradiation, them dried in an oven at 600 °C for 2 h. The NPs were characterized by X-ray diffraction (XRD), Field emission scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and optical absorption (UV–Vis) measurements. A single-phase cassiterite type tetragonal structure with (110), (101), and (211) planes was observed in pure and Fe-doped NPs, as revealed by XRD analysis. FESEM results show ultrafine NPs with sizes around 27 nm and spherical in shape in both pure and Fe-doped samples. The direct optical band gap of SnO2 NPs were 3.4 eV and increased doping concentration of 0% to 3% resulted in a decrease in the direct optical band gap from 3.4 to 3 eV. The stretching vibration peak of Sn-O-Sn is 670cm-1. |
