α-Fe₂O₃ / ZnO multilayer films fabricated by using spin-spray method and properties of each layer and α-Fe₂O₃ / ZnO film were investigated. First, as-deposited ZnO layer on glass substrate exhibited high transmittance of above 80 % in visible range and a low resistivity. The formation of α-Fe₂O₃ layer on glass substrate was confirmed by XRD. This α-Fe₂O₃ layer was successively deposited on ZnO layer and it was confirmed that α-Fe₂O₃ / ZnO double layered films could be fabricated by aqueous solution process.
