Tin oxide is a wide band gap semiconductor for which the band gap can be tuned upon doping.  The synthesis and ready availability of monodisperse uniformly shaped tin oxide nanoparticles is needed for applications requiring stable dielectric materials either in solution, in bulk, or deposited as films on substrates.  To this end, this presentation describes simple and reproducible procedures for the hydrothermal synthesis of uniform monodisperse tin oxide nanoparticles and doped tin oxide nanoparticles.  The tin oxide nanoparticles were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-Ray photoelectron spectroscopy (XPS).  In addition, their optical properties were evaluated by UV-vis spectroscopy and diffuse reflectance spectroscopy (DRS).  The band gap of the tin oxide nanoparticles was successfully tuned upon doping, which led to enhanced absorption/extinction in the visible region.  A complete summary of the physical properties and potential applications will be described.
