Characterization of ATO NPs

So far, we noticed the absence of light soaking and photo-shunt as potential advantages of n-type SnO2 NPs over ZnO-based ETMs. Next, we extended our investigations to the ATO NPs and clarified the nature of the polarity and the doping mechanism. We selected Sb3+for two reasons: firstly, Sb3+is expected to be a p-type dopant as compared to Sb5+; second, Sb3+(0.76Å) has an ion radius that is comparable to that of Sn4+(0.69Å), potentially facilitating substitutional doping rather than interstitial

Antimony Tin Oxide

What is ATO?ATO (Antimony Tin Oxide) is a highly insoluble, thermally stable Aluminum source suitable for glass, optic and ceramic applications. ATO is available in granule, powder, and tablet forms. Oxide compounds are not conductive to electricity. Used exclusively in electronics and optics, antimony-tin oxide, or ATO, is an important component of display panels due to its antistatic, infrared absorbance, and transparent conductivity. Tin(IV) oxide can be used as a polishing powder, sometimes
