Abstract
Nanoclusters of SnO2 were synthesized using sol gel technique. The solution containing SnO2 nanoclusters was spin coated on Pt inert digital electrodes/glass substrate to deposit thin film of semiconducting nanoclusters of SnO2 (200nm). TEM images and electron diffraction pattern were studied to find out the size and polycrystalline nature of Tin oxide nanoclusters. The SnO2 thin film was used for NO2 gas sensing and was found to be highly sensitive to detect ultra-low concentrations (ppb range) of NO2 at room temperature.
