Abstract
This study reports the preparation and gas-sensing performanance of thick film coppergermanate (CuGeO3) based gas sensor. The structural and microstructural properties of CuGeO3 material have been characterized using by various analytical practice. Thick films of the material were prepared by screen printing technique. The electrical resistance response of the sensor was investigated for different gases like H2S, LPG, CO, CO2, O2 and NH3 at different operating temperatures ranging from room temperature to 450oC. Selectivity and sensitivity of CuGeO3 is measured and reported. The material shows negative temperature coefficient. The synthesized sensor shows excellent electrical resistance response toward H2S gas.
