Abstract
Nanosized stannic oxide particles modified with a layer of DBS were su ccessfully prepared through the colloidal chemical method and their mi crostructures were characterized. FTIR and XPS were used for the deter mination of the main components. It can be proved that the nanosized S nO2 particles were capped by DBS. The sizes of particle were determine d by TEM and XRD. By the investigation of XPS, we can conclude that th ere are a lot of oxygen vacancies in the surface of the nanoparticulat es. Based on this conclusion, the ESR signal of the sample can be expl ained.
