Electroless deposition of Sno2 and antimony doped SnO2 films

Thin polycrystalline films of SnO₂ and antimony doped SnO₂ have been prepared by simple economic electroless deposition technique. The transmittance in the visible range and the reflectance in the i.r. range for SnO₂ films are ～80% and ～70%, respectively, with resistivity ～10^?2 Ω cm. On the other hand, antimony doped SnO₂ films have transmittance in the visible range and reflectance in the i.r. range, as good as ～86% and ～83%, respectively, with resistivity as low as ～10^?3Ω cm. By vacuum annealing, the resistivity of both types of films has been brought down as low as ～10^?3 and ～10^?4 Ω cm, respectively.
