In this work we present the results of the pH effect on the synthesis of Sn02 by precipitation. This simple chemical route allowed us to obtain Sn02 nanocrystals whose grain size depends linearly on the pH, ranging from 3 to 8nm, from basic to acid solutions, respectively. The most important, microstructures were also fabricated by this simple method, mainly whiskers and long fibers. The crystalline quality and the morphology were confirmed by X-ray diffraction and electron microscopy. The samples showed high-energy optical absorption as observed by UV-Vis measurements.
