Antimony doped SnO2 films have been prepared by spray pyrolysis. The films deposited at an optimised substrate temperature of 520 degrees C were found to have a resistivity as low as 0.4 x 10(-4) Omega cm. Doping concentration of Sb in the spraying solution was varied from 0.5 to 5%, keeping the spray rate constant. The sheet resistance was as low as 6 Omega cm(-2). About 80% average transmission in the visible region was obtained for 1% Sb doped films. The refractive index increased from 1.62 to 2.64 with increasing the Sb content from 0 to 5%. Van-der-Pauw's four probe technique of conductivity measurement was used to measure electrical conductivity (sigma), Hall coefficient (R-H), carrier concentration (n) and Hall mobility (mu(H)) of the Sb:SnO2 films. The hims deposited using 1% Sb doping showed the best properties.
