Study of ATO nanoparticles by the solvothermal method for thermal insulated coated glass: a green energy application

Abstract

Antimony-doped tin oxide (ATO) nanoparticles (NPs) (Sb-doped content 3%, 10%, and 15%) were synthesized by the (2 l autoclave, medium-scale) solvothermal method followed by sintering at various temperatures (500°C, 800°C, 900°C and 1000°C) so they would crystallize. The particle size increased from several to tens of nanometers with the increase of sintered temperature from 500°C to 1000°C, sharply from 800°C to 1000 °C; ~30 g of final product was received for each experiment. More interestingly, the crystallinity of the as-synthesized ATO was also increased with the increasing Sb doped content from 3% to 15%. The ATO NPs were coated onto glass substrates and then sintered at 500°C, which effectively prevented transmittance of infrared (IR) wavelengths (>800 nm) with 10% wt Sb-doped content, which is useful for thermal insulated glass coating application.
