Abstract
In this piece of work, we have synthesized pure and aluminum doped zinc oxide and then studied their sensing response towards ethanol. We adopted a chemical route to synthesize pure and aluminium doped ZnO, in this work we added different concentrations of aluminum by weight (1% to 4% by percentage weight). The XRD studies revealed that synthesized materials are having wurtzite hexagonal crystalline structures. With the addition of dopant the crystallinity of the structures has decreased. FESEM images have clearly shown the modification of morphology of material with the addition of the dopant. With the addition of dopant sensing responses also have changed significantly.
