Characterization of ion track morphology formed by swift heavy ion irradiation in silicon oxynitride films

EPJ Web of Conferences, 2015
Amorphous silicon oxynitride (SiOxNy) possess interesting optical and mechanical properties. Here, we present direct evidence for the formation of ion tracks in 1 µm thick silicon oxynitride of different stoichiometries.

Counterevidence to the ion hammering scenario as a driving force for the shape elongation of embedded nanoparticles

AIP Advances, 2017
Counterevidence is provided in the ion-hammering scenario as a driving force for the shape elongation of embedded nanoparticles (NPs) under swift heavy ion irradiation (SHII).

Making tracks in metals [PDF]

, 2008
Swift heavy ions lose energy primarily by inelastic electronic scattering and, above an energy threshold, electronic losses result in damage to the lattice.

Insights into nanoparticle shape transformation by energetic ions

Scientific Reports, 2023
Shape modification of embedded nanoparticles can be achieved by means of swift heavy ion irradiation. During irradiation, the particles elongate and align with the direction of the ion beam, presumably due to nanometer-scale phase transitions induced by ...

Analysis and optimization of propagation losses in LiNbO3 optical waveguides produced by swift heavy-ion irradiation [PDF]

, 2012
The propagation losses (PL) of lithium niobate optical planar waveguides fabricated by swift heavy-ion irradiation (SHI), an alternative to conventional ion implantation, have been investigated and optimized.

Assessing TiO2/Chitosan‐Based Hydrogels for Water Remediation: Sunlight‐Driven Degradation of Antibiotics in Water

Advanced Materials Interfaces, EarlyView.
Chitosan–TiO2 composite hydrogels combine adsorption of organic pollutants with photocatalysis, allowing to remove 85% of a broadly diffused antibiotic (sulfamethoxazole) under direct sunlight irradiation, opening great promises for point‐of‐use, outdoor applications.

Au9+ swift heavy ion irradiation of Zn[CS(NH2)2]3SO4 crystal: Crystalline perfection and optical properties

, 2014
The single crystal of tris(thiourea)zinc sulphate (Zn[CS(NH2)2]3SO4) was irradiated by 150 MeV Au9+ swift heavy ions and analyzed in comparison with pure crystal for crystalline perfection and optical properties.
