Synthesis and structural characterization of tungsten trioxide nanoplatelet-containing thin films prepared by Aqueous Chemical Growth

► WO3 thin films grown on glass slides by Aqueous Chemical Growth, at 90-95 °C ► Formation of square-nanoplatelets in the thin films is confirmed. ► Raman spectroscopy confirms platelets to be monoclinic in crystal structure. ► Drop-coated thick films of WO3 nanoplatelets on glass, sensed H2 at 300 °C
