Porous screen printed indium tin oxide (ITO) for NOx gas sensing
View through CrossRef
AbstractTin‐doped Indium Oxide (ITO) films were prepared by the screen printing method. Transparent and conductive ITO thin films were obtained from an organometallic based paste fired in an Infrared furnace. The Screen printed ITO films were found to be granular and porous. This specific morphology was found to be suitable for sensing different gaseous species. This work investigates the possibility of using screen printed (ITO) films as a specific material for efficient NOx gas sensing. It was found that screen printed ITO is highly sensitive and stable towards NOx, especially for gas concentration higher than 50 ppm and starting from a substrate working temperature of about 180 °C. The sensitivity of the ITO films increases with increasing NOx concentration and temperature. The sensitivity and stability of the screen printed ITO based sensors were studied within time. The ITO crystallite grain size dimension was found to be a key parameter that influencesè the gas response characteristics. Maximum gas sensitivity and minimum response time were observed for ITO films having lower crystallite size dimensions. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
