摘要：

The aligned SnO2 nanotube arrays on Si substrate have been prepared via liquid-phase deposition with the solution system of SnF2 utilizing ZnO nanorod arrays as sacrificial template. The SnO2 nanotubes are distributed uniformly and grown perpendicularly to the substrate. The SnO2 nanotubes are rutile phase with the outside diameter of similar to 190-310 nm and the wall thickness of similar to 45 nm. The template-related growth mechanism for the formation of SnO2 nanotube is investigated. Experimentally, the SnO2 nanotube array shows an efficient field-emission property, which is favorable for realizing high performance cold cathode electron emitters. (C) 2013 Elsevier B.V.
