Samples of ferrite spinels doped with manganese cations were obtained via organic co-precipitation, and their structure, morphology and magnetic properties were studied.
5% Fe and Mn-doped nano ZnS (Zn0.95A0.05S, A=Fe or Mn) was prepared using the thermolysis technique. The effect of Fe and Mn doping on the lattice parameter, crystallite size, and lattice microstrain was examined applying Rietveld refinement. The analysis showed the incorporation of Fe and Mn substitutionally for Zn ions; a result confirmed by Fourier transforms infrared spectroscopy spectra from the shift in the vibration bands upon doping. The energy of ZnS band gap was reduced by doping, giving ZnS new applications. The different defects inside the different samples were investigated using photoluminescence spectroscopy. The effect of Fe/ Mn doping and incorporation of atmospheric oxygen on the bandgap characteristics, the absorption, optical conductivity, refractive index and the extinction coefficient, reflectance, the real and imaginary parts of the dielectric constant were explored using density function theory calculation (DFT).

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
