Abstract
In this study, hematite (α-Fe2O3) nanostructure were prepared in Schott vials on fluorine-doped tin oxide (FTO) coated glass substrate using the sonicated immersion method in aqueous solution with ferric chloride FeCl3⋅6H2O as a precursor and urea NH2−CONH2 as a stabilizer. The samples were characterized for different level of humidity conditions within range 40% to 90% RH. Based on the results obtained, the hematite nanostructure exhibited good optical properties and virtuous sensor response with high sensitivity. The fabricated hematite nanostructure has revealed a good potential for humidity sensor application based on the results obtained under different levels of humidity.
