Effect of pH of colloidal suspension on crystallization and activation energy of deep levels in SnO2 thin films obtained via sol-gel
(Journal of Physics and Chemistry of Solids, 2009-09-01) [Artigo]
Colloidal suspensions of tin dioxide (SnO2) are prepared by the sol-gel method from suspensions with distinct pHs. The particles in solution are embedded by an electrical layer. Decreasing the pH contributes to the destruction ...
