Abstract
In the present work, we have successfully synthesized a large scale of 3D dendritic α-Fe2O3 structures via a simple hydrothermal reaction through hydrolysis of K3Fe(CN)6 precursor. The crystallinity, composition and morphology of the synthesized sample have been characterized by powder X-ray diffraction (PXRD), field emission scanning electron microscopic (FESEM) and energy dispersive X-ray spectroscopic (EDS) techniques. PXRD study indicates that it is well crystalline and single phase in nature. FESEM images reveal that the shape of the sample is dendritic structured with symmetric branches along each arm consists of a long central trunk with secondary branches. The optical properties have been performed by UV-Vis and a photoluminescence (PL) spectrum, where UV-Vis spectra showing visible light absorption and PL exhibiting a peak near UV region indicates up-conversion property. So, we can use this sample for visible light mediated catalysis applications, photodectector and photo-voltaic application purposes.
