Formation of transparent conducting SnO2 films by partial sublimating of tin xerogel and its application
(0) A novel experiment method for formation of a transparent conducting tin dioxide by partial sublimating process of tin xerogel is introduced in this article. The matter of the sublimating tin xerogel has been deposited on quartz substrates or silicon wafers. A conducting SnO2 film with transmittance of over 80 ％ in the visible range has been obtained on a quartz substrate. Atomic force microscopy (AFM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), ultraviolet (UV)-visible transmittance spectra and sheet resistance measurements have been used to analyze the morphology, structure, composition, optical and electrical properties of the deposition films. The phenomenon of partial sublimating of the tin xerogel has been used to modify the surface of ZnS phosphor powders. The electrical conductivity of the modified ZnS:Mn phosphor powders has obviously been improved when the mass ratio of SnO2 xerogel to ZnS:Mn phosphor powders and heat treatment temperature were 3.0 and 500 ℃, respectively.
