Photoluminescence and Raman studies for the confirmation of oxygen vacancies to induce ferromagnetism in Fe doped Mn:ZnO compound

Search for Origin of Room Temperature Ferromagnetism Properties in Ni-Doped ZnO Nanostructure

“…42 In comparison with earlier reports of ZnO, two LO modes are located at 587 cm −1 (E 1 ) and 575 cm −1 (A 1 ). 44,45 These LO modes arise due to defects such as V O and Zn in or free carriers present in ZnO nanostructure. 46 Transition metal (such as Fe and Mn) replacement in ZnO, shows significant modification in the E 1 (LO) mode because of variation in inherent host lattice defects.…”

Reduction of hazardous reactive oxygen species (ROS) production of ZnO through Mn inclusion for possible UV-radiation shielding application

“…Both the E 2H and 3E 2L peaks were slightly shifted towards lower frequencies for the Mn-doped ZnO. Vladut et al (2018) [25] and Das et al (2015) [40] also reported some peak shifting when doping ZnO with Mn ions, which they said was an indication of tensile stress induced in the crystal. Ahmed and co-authors [26], further highlighted that impregnating transition metals in the ZnO lattice leads to microscopic topological and structural disorders in the periodic Zn atomic sub lattice and breaks translational symmetry.…”
