Abstract

Abstract: Nanosized stannic oxide particles modified with a layer of DBS were successfully prepared through the colloidal chemical method and their microstructures were characterized. FTIR and XPS were used for the determination of the main components, It can be proved that the nanosized SnO₂particles were capped by DBS. The sizes of particle were determined by TEM and XRD, By the investigation of XPS,we can conclude that there are a lot of oxygen vacancies in the surface of the nanoparticulates, Based on this conclusion,the ESRsignal of the sample can be explained.

Key words: Surface modification, Nanosized particles, Microstructural characterization, SnO₂
