“…On the other hand, the contribution of plasmonic absorption from Ag nanoparticles can be observed as an increment in the optical absorption of the Ag/ZnO nanoparticles in the near UV/visible region. Similar results showing the improvement in the absorption near UV/visible region for Ag/ZnO nanoparticles are also reported previously [46][47][48][49][50]. The UV-vis results indicate that the presence of Ag nanoparticles significantly increases the optical absorption of Ag/ZnO nanoparticles in the visible light region of solar spectrum.…”

“…The second absorption band detected with a maximum absorption peak (λ max ) in the range 320 to 480 nm had a symmetric shape and appeared a few minutes after the rosemary EO had been added and grew continuously for 30 min (reaction time), while no significant changes were observed afterwards. This band corresponds to the surface plasmon resonance (SPR) of the growing silver nanoparticles …”

“…The shape of the SPR is sensitive to the size, shape and environment of metal nanoparticles . In particular, symmetric and narrow shapes of the absorption peaks highlighted the presence of well‐defined morphologies, such as spheres or ellipsoid particles without or with minimal intra‐particle aggregation .…”

A green and fast methodology was developed to synthesize silver nanoparticles using rosemary essential oil (EO) as a renewable reducing agent. The synthesis process was microwave (MW) assisted, using a coaxial dipole antenna immersed into the reaction medium. This configuration was used to promote both: i) rosemary EO extraction by hydrodistillation, and ii) silver nanoparticle synthesis in an aqueous solution at atmospheric pressure. The effect of two different silver salt substrates and the time reaction on the morphology of the silver nanoparticles was explored. The coaxial microwave‐assisted hydrodistillation of rosemary yields 0.4 % (w/w) in 30 min and contains ethers (17 %), ketones (50 %) and alcohols (15 %). Silver nanoparticles with a tuneable particle size (from 7 to 18 nm) and morphology (from spherical to round‐like shapes) were obtained in reaction times ranging from 2 to 30 min. The nanoparticle formation was followed by UV‐vis spectroscopy and SEM imaging.

“…This means shorter interparticle spacing has a stronger near-field coupling, which generates a larger red shift. Previous research [22] showed that in the dense array of 8 nm sized Ag NPs generated by cluster beam deposition, with the increase of the NP density, the SPR wavelength demonstrated a red shift from less than 400 nm to more than 570 nm, in accompanying with an increased broadening of the resonance peak.…”

Ultraviolet irradiation was used to tailor the surface plasmon band of the densely distributed aluminium nanoparticle arrays fabricated by gas-phase deposition. We showed that the broad surface plasmon resonance band of the as-prepared sample could be tuned to a sharp and strong resonance band in the deep ultraviolet optical range, with a large blue shift of the peak wavelength. The evolution of the surface plasmon resonance properties was attributed to the ultraviolet irradiation-improved surface oxidation of the nanoparticles, which eliminated the near-field couplings between the closely spaced nanoparticles by increasing their interspacing.
