Environmentally friendly improvement of plasmonic nanostructure functionality towards magnetic resonance applications

Popis výsledku v původním jazyce

Advantage of pulsed laser ablation in liquids is the possibility to controllably produce plasmonic nanoparticles in combination with other plasmonic or magnetic materials,thus enhancing their functionality.However,the PLAL technique is still challenging in respect of merging metallic and semiconductor specific features in nanosized obj. that could significantly broaden appl. areas of plasmonic nanostructures.We performed synthesis of hybrid AuSi NPs with novel modalities by ultrashort laser ablation of bulk gold in water containing silicon NPs.The Au/Si atomic ratio in the nanohybrids was finely varied from 0.5 to 3.5 when changing the initial Si NPs concentration in water from 70µg/mL to 10 µg/mL,without requiring any complex chemical procedures.It has been found that the laser-fluence-insensitive silicon content depends on the mass of nanohybrids.A high concentration of paramagnetic defects(2.2·× 1018 spin/g) in polycrystalline plasmonic NPs has been achieved.n
