Abstract
A novel and facile synthesis route for the manufacture of transparent and uniform self-assembled nanocrystalline Cr2O3 (nc-Cr2O3) thin films with different morphology was reported, utilizing chromium nitrate as the inorganic source and triblock copolymer F127 as the morphology-directing agent by the evaporation-induced assembly (EIA) method. X-ray powder diffraction (XRD), thermogravimetry-differential scanning calorimetry (TG-DSC), N2-sorption, scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used to characterize the as-prepared nc-Cr2O3 thin films. The Cr2O3 thin film with different morphology was obtained by changing the relative humidity. The possible formation mechanism of the nc-Cr2O3 thin films with different morphologies was discussed.
