Figure 1From: Role of vanadium ions, oxygen vacancies, and interstitial zinc in room temperature ferromagnetism on ZnO-V2O5 nanoparticlesRaman spectra of pure ZnO samples under different synthesis conditions. Samples ZnO.Com, ZnO.Et, ZnO, and ZnO.Et.Cal. Sample ZnO (dry milled) has very different behavior than the rest of the samples; additional peaks are attributed to Zni impurity complexes.Back to article page
