  We investigate the effect of controlled annealing on the structural and
electronic phase evolution of Tin dioxide from Tin (II) oxyhydroxide prepared
by simple precipitation method. Thermogravimetric analysis suggests a complex
weight loss-gain process involved, passing through an intermediate phase of tin
oxide nanoparticles. The probable structural and electronic phase evolution is
discussed using detailed X-ray diffraction and X-ray photoelectron spectroscopy
investigations.
