Study and Characterization of Zn-Bi2O3 Nanocomposite Using Theoretical and Experimental Method

Abstract

Bi2O3 nanoparticle is the promising material for various applications because of its noble properties. In this study, we studied the properties of Bi 2O3 based nanocomposite using experimental and theoretical method. We synthesized based nanocomposite particle using biological and chemical synthesize technique. The synthesized nanoparticles were characterized using PL spectroscopy and XRD. From the characterization methods, we got the expected result. We also investigated theoretically the optical properties of Zn- nanocomposites which embedded non-absorptive passive medium as a host matrix. The polarizability, refractive index, and optical absorbance of the composite nanostructures are investigated using the Maxwell- Garnet effective medium theory within the framework of the electrostatic approximation. The simulations were performed using the wolfram Mathematica software. We observe that two set of resonance peaks in the visible (above 300 nm) and visible-near infrared (between 450 − 600 nm) spectral region for different values of metal fraction and filling factor. These two set of resonances are appeared almost at the same positions for all polarizability, refractive index, and optical absorbance. The effect of the permittivity of the medium, the size of the core, and the shell on the extinction spectrum and the refractive index were investigated.
