Abstract in another language
A method for preparing sol-precipitated Sr(Ti0.8Fe0.2)O3-δ powders yielding particle sizes of about 70 nm is presented. Screen-printed films based on such nanoscaled powders are compared and contrasted to conventional micro-scaled thick films. By employing sol-precipitated powders, the hydrocarbon sensitivity of the sensor devices was improved. For unsaturated hydrocarbons, resistance changes similar to those of thin films prepared by pulsed laser deposition were observed, thus combining the fast sensor response of Sr(Ti0.8Fe0.2)O3-δ thick films with the high R/R0 values observed for thin films.
