The influence of the incorporation of Mn atoms in CdO nanoparticles on structural pathways, linear, and non-linear optical characteristics for optoelectronic devices
Research Description
The paper discusses the synthesis and characterization of Cd1-xMnxO nanoparticles
using the precipitation method for potential optoelectronic applications. X-ray diffraction
analysis revealed a cubic polycrystalline structure, with a decrease in crystallite size
as Mn concentration increased. UV–Vis spectroscopy data showed changes in the band
gap with varying Mn concentrations, with Eopt.
g decreasing from 2.523 eV to 2.304 eV as
Mn content increased up to 3%. However, with further increases in Mn content, Eopt.
g
increased to 2.332 eV. The study also estimated various optical properties, providing
valuable insights into the optical behavior of Cd1-xMnxO nanoparticles. In addition to
the aforementioned characterizations, the paper explores the influence of Mn content on
dispersion parameters using Wemple Di-Domenico models. The dispersion energy (Ed)
was found to increase from 13.502 eV to 14.170 eV, while the single oscillator energy (Eo)
decreased from 3.483 eV to 3.142 eV with increasing Mn content. This suggests that the incorporation of Mn into CdO alters its optical properties significantly. Furthermore,
the study calculated non-linear optical coefficients, such as the third-order non-linear
susceptibility (?(3)) and non-linear refractive index (n2), for CdO nanostructured powder
doped with Mn. These findings indicate the potential suitability of Cd1-xMnxO
nanoparticles for applications in the fields of optics and electronic devices, highlighting
their potential for use in advanced technologies requiring tailored optical properties and
nonlinear behavior.
