The elemental distributions of bismuth crystal were observed by scanner electron microscope. The crystal structure was confirmed with X-ray diffraction. Many spectroscopic methods, such as dynamic light scattering, F-IR, XRD and UV-Visible spectroscopy were used to determine the samples.
The spectrum of absorption of UV-visible light was researched to determine the UV protective properties of the nanoparticles. The wavelength for UV absorption is between 250-700 nm. The absorption peak of bismuth oxide is at 300 nm.
The antibacterial activity of the nanoparticles were also investigated using an approach to diffusion of disks. Bismuth's antibacterial properties oxide was assessed with respect to Salmonella ATCC 1231. It was stained on the discs with different concentrations of samples. The diameter of the area of inhibition was determined using the ruler.
This green process for synthesising nanoparticles have gained a lot of interest in recent times. It has been used for various applications in food industry and pharmaceutical industry.
Bismuth oxide nanoparticles are also utilized for UV blocking. They are extremely pure and can be used for antibacterial function. Bismuth oxide is a photocatalyst with a wide absorption spectrum and has the capacity of removing organic molecules. It is also used to treat water.
