“…The appearance of AM for the doped samples can be taken as an indication of Mn incorporation into the ZnO lattice, because these modes were absent in the Raman spectra of the undoped ZnO NRs. Similar AM have already been observed at 525 cm −1 for Mn-doped ZnO nanowires and attributed to the presence of Mn ions or Mn-doping-induced defects in ZnO [ 54 ]. Recently, Raman measurements of high-quality ZnMnO films grown by OPAMBE revealed two local vibrational modes (LVMs) which is attributed to Mn-(Zinc-vacancy) complexes (at 523 cm −1 ), and the LVM at 712 cm −1 is attributed to Mn-(Oxygen-vacancy) complexes [ 31 ].…”

“…The strong peak at 210 cm -1 referring to the 2E 2L second-order phonon mode emerged [44]. The E 2H modes became weak with the incorporation of metallic ions into the host matrix, which can be attributed to structural defect formation and local distortions induced by doping [14,45]. Additionally, any additional Raman modes associated with the presence of secondary phases were observed, in good accordance with XRD results.…”

“…Doping ZnO with magnetic ions is an interesting alternative to enhance ferromagnetic properties, as well as optical and electrical properties, which are crucial for its practical applications [14][15][16]. Previous works have demonstrated the influence of Co 2+ and Ni 2+ ion doping on the optical properties of semiconducting oxides, providing the formation of multi-emission centres in the final materials, and promoting a chargetransfer state just below the band-gap energy [17][18][19].…”

“…The magnetization property of the three samples was further studied using the standard zero field cooling (ZFC) and field cooling (FC) protocols under an applied magnetic field of 1000 Oe between 5 and 300 K, as shown in Figure f. All the samples exhibit a paramagnetic‐like Curie‐Weiss behavior . However, apparent divergence of the FC and ZFC magnetizations for the samples prepared at 160 (up to 250 K) and 180 °C (up to 125 K) can be observed, which can exclude the para‐ and diamagnetic contributions to the hystersis loop and thus further confirms the ferromagnetism of the as‐made Pt nanostructures.…”
