In this paper, the results of barium oxide doped indium oxide films as sensor material for monitoring ppm levels of NOx (a mixture of NO and NO2) in ambient have been presented. The parameters for obtaining nanostructured and textured thin films of Ba doped In2O3 using pulsed laser deposition (PLD) technique have been optimized. These films are found capable of sensing down to 0.5 ppm NOx concentration...
Pulsed laser deposition (PLD) of MoO 3 thin films and their gas sensing properties are reported. As-deposited films were found to be a mixture of sub-oxides. Post-annealing of the films in air at 773K for 5h transforms the sub-oxides to MoO 3 with diminished intensities of (0k0) reflections. The microstructure of the films were investigated by scanning electron microscopy and atomic...
