Abstract:Tin oxide with rutile-type crystalline structure is a n-type wide band gap (3.5 eV) semiconductor that presents a proper combination of chemical, electronic and optical properties that make it advantageous in several applications. Due to its physical properties, such as transparency and semiconductivity, it is an oxide of great interest from the technological point of view for gas sensors, white pigments for conducting coatings, transparent conducting coatings for solar cells, catalysts, varistors; an increasing interest in the use of anodes of SnO2 in lithium batteries has been recently noticed. In this contribution we present the obtaining of SnO2 nanoparticles with average diameters of 5 nm by hydrothermal route from SnCl2 and temperature of 200 C. The nanostructures were studied by UV-visible electronic absorption and Raman spectroscopy [1], their crystal structure were determined from XRD patterns and by HRTEM images XRD showed the presence of single phase of cassiterite structure, as found from XRD line broadening the crystallite sizes of all powders were in the nanometric range.
