Abstract
In2O3 thin films on sapphire substrates have been prepared from indium isopropoxide solutions by sol-gel process. Highly sensitive films have been obtained by using aged solutions and 500°C annealing temperature. The electrical resistance increases greatly with increasing ozone concentration in the ppb range. The sol-gel-derived sensors have ozone sensitivity as large as 6 at 45 ppb, and working temperature below 200°C
