摘要：

Semiconducting tin dioxide incorporated with specific additives has been prepared by the technique of sol-gel to achieve particle sizes in the range of nanometers. This reduced size has been shown to significantly improve the gas sensing characteristics of the sensor elements. Sensitivity of tin dioxide doped with CuO prepared by this method shows an increase in sensitivity over the same composition obtained by conventional hydrolysis method. The results clearly brings out the influence of the crystallite size on the gas sensing characteristics of sensors based on these semiconducting materials. (C)1999 Acta Metallurgica Inc.
