Abstract
The effect of ppm level H2 on the d.c. resistance of SnO2 thick film planar resistor with SnO2 particle size variation (~ 20 to 50 nm) is reported. SnO2 nanoparticles were synthesized using the sol-gel method. The films were prepared using standard screen printing technology. The SnO2 crystallite size, D, is varied in the range of 20-50 nm and sensitivity for H2 is found to increase steeply as D decreases.
