Preparation of Sno2 nanomaterials
In this study, Sno2 nanofilms were prepared by the sputtering method, and Sno2 nanorods and nanowires were synthesized by the rhermal evaporation method. In the case of the Sno2 nanofilms, the films were depositer on oxidized Si substrates at a discharge gas pressure of 24 Pa and a substrate temperature of room temperature (25 องศาสเซลเซียส)by reactive dc magnetron sputtering.
