The authors have investigated a new chemiluminescence (CL)-based gas sensor made of aluminum oxide ({gamma}-Al{sub 2}O{sub 3}) which emits CL during the catalytic oxidation of combustible vapors in air. The CL intensity is proportional to the concentration in the wide region from 1 to 1000 ppm of ethanol, butanol and acetone in air. However, it has a tendency to saturate in concentrations above 1000 ppm. For the detection of vapors in the environmental atmosphere, improvements of the sensitivity and the linear characteristics of the sensor are necessary. Catalytic reaction processes on the sensor were studied for this purpose.
