Enhancement of infrared shielding property of SnO₂ using Sb as a dopant

Abstract Transparent conducting oxides (TCO) are essential to the operation of advanced energy harvesting and storage devices, as well display technology. Doped tin oxide (SnO 2 ) exhibits enhanced optical thermal characteristics in comparison undoped SnO . In this article, cost-effective sol-gel methodology was employed synthesis antimony (Sb) doped nanoparticles. According XRD analysis, tetragonal structure maintained despite apparent reduction crystal size amount Sb increased. study, effect that doping has on absorption reflection visible near-infrared regions analyzed. The band gap nanoparticles observed broaden concentration increased from 3.44 eV (ATO-0) 4.62 (ATO-6). results UV–vis-NIR spectra demonstrated ATO films efficiently reduced infrared light passed through them. heat-insulation test showed ATO-coated glass outperformed uncoated terms heat insulation. Because these characteristics, could be a good replacement material, especially for solar cells smart windows.
