Description
Summary:In this work pure CuCr 2 O 4 and Mn-doped CuCr 2 O 4 nanoparticles were prepared using Microwave combustion process. The phase analysis of the prepared samples is investigated using X-Ray Diffraction technique and an decrease in particle size observed from ∼37 to ∼26 nm with rise in Mn doping concentration. Further optical data revealed the presence of multiple Mn-related optical centres . Morphological studies revealed the prepared samples exhibited irregular plate-shaped agglomerates. Furthermore, the antibacterial performance of undoped CuCr 2 O 4 and Mn-doped CuCr 2 O 4 samples are investigated. At 500 °C, the electrical conductivity for the CuCr 2 O 4 and Mn-doped CuCr 2 O 4 samples were found to be 0.98 × 10 −2 S/cm and 2.13 × 10 −2 S/cm respectively. The activation energy of the pristine CuCr 2 O 4 and Mn-doped CuCr 2 O 4 samples was found to be 0.87 eV and 0.69 eV respectively.
