Description
Summary:•Combined experimental and theoretical researches of Cauliflower-like Bi2O3 nanostructures.•Analyze the optical and structural properties of Bi2O3 nanostructures.•Characterize the Bi2O3 nanostructures of 2 and 3-D.•Verify refractive index and optical dielectric constant of Bi2O3 nanostructures.•Investigate the energetic transition for improving solar cells performance. Cauliflower-like Bi2O3 nanostructures was prepared using pulsed laser deposition (PLD) at different oxygen pressure. Atomic force microscopy (AFM) has revealed nanostructured film at grain size ranges from 97.5nm, 65.12nm. X-ray diffraction (XRD) displays polymorphous Bi2O3 of different phases of stoichiometric and non-stoichiometric structures. Optical analysis has been elaborated at different pressures. Scanning electron microscopy (SEM) shows Cauliflower-like Bi2O3 nanostructures. The refractive index and optical dielectric constant are calculated using specific models and showed good agreement with other result.
