Fe-doped nanosized SnO 2 powders were prepared by mechanosynthesis using rutile SnO 2 and hematite Fe 2 O 3 as starting materials. The estimated grain size of the obtained rutile structure was between 10 and 20 nm. Mo¨ssbauer spectroscopy shows the presence of two interactions corresponding to 3+ an
The effect of thickness on the p.p.m, level H2 gas sensitivity of SnO2 nanoparticle-based thick film resistors is reported. The nanoparticles are synthesized by a sol-gel method and the films are prepared using standard screen printing technology. The thickness of the films is varied from a few micr
