- Zn1âxMnxO nanoparticles were synthesized by pulsed laser ablation in liquids.
- In SEM images flower-like nanostructures were revealed.
- Absorption edge of Zn0.95Mn0.05O nanoparticles exhibits blue shift due to confinement effect.
- The Faraday rotation studies confirm paramagnetism of Zn0.95Mn0.05O nanoparticles.
Nanoparticles of ZnO and Zn1âxMnxO were synthesized by pulsed laser ablation in liquid medium (PLAL). Metal zinc target was used for preparing of pure ZnO nanostructures and Zn1âxMnxO ceramic plates served for preparing of ternary nanoparticles. As synthesized nanomaterials are characterized using scanning electron microscopy (SEM), energy dispersive spectroscopy analysis (EDS), atomic force microscopy (AFM), UV-vis absorption, photoluminescence and Faraday rotation spectroscopy. SEM images showed a well-defined flower-like nanostructures. Absorption edge of Zn0.95Mn0.05O nanoparticles in colloid solution exhibits blue shift due to confinement effect. The observed photoluminescence peaks are attributed to the band-edge transitions and vacancies or defects. The Faraday rotation as a function of photon energy demonstrates behavior typical for diluted magnetic semiconductors (DMSs) in paramagnetic state.
