Abstract
Different morphologically varied α-Fe2O3 nanocrystals have been successfully synthesized by a solvothermal route. X-ray diffraction patterns, transmission electron microscopy and field emission scanning electron microscopy have been employed for structural and morphological characterization. Various unique shapes of the well crystalline α-Fe 2O3 phase has been revealed and the evolution of crystal growth with different morphology is explained on the basis of oriented attachment mechanism controlled by different solvents used in the reaction. The effect of morphology of α-Fe2O3 nanocrystals on their optical absorption behavior has been observed and the absorptions were analyzed considering all the possible electronic transitions in such 3d 5 systems.
