Description

tin oxide (SnO₂) nanostructures were synthesized using chemical bath method and DC magnetron sputtering. SnO₂ oxide nanostructures were deposited at different temperatures (300 ^oC, 400 ^oC, and 500 ⁰C. XRD results shows that as the temperature increases also the cystalinity increases. SEM results also show that particle sizes increase with the increase in temperature. EDS show that the ratio of tin to oxygen is as expected to be. More studies will be carried out on the samples as to show the effect of doping on gas sensing ability of SnO₂. It was found that the temperature has the effect on nanoparticle sizes and their crystalinity. we bilieve doping nanoparticle will enhance the gassing sensitivity of Tin Oxide nanostructure.
