Journal ArticleDOI
Controlled anisotropic deformation of Ag nanoparticles by Si ion irradiation
Alicia Oliver,Jorge-Alejandro Reyes-Esqueda,Juan Carlos Cheang-Wong,Carlos E. Roman-Velazquez,Alejandro Crespo-Sosa,Luis Rodríguez-Fernández,J. A. Seman,Cecilia Noguez +7 more
TL;DR: In this article, the shape and alignment of silver nanoparticles embedded in a glass matrix is controlled using silicon ion irradiation, and they are transformed into anisotropic particles whose larger axis is along the ion beam.
Journal ArticleDOI
Enhanced Fano Resonance in Asymmetrical Au:Ag Heterodimers
Ovidio Peña-Rodríguez,Umapada Pal,Mariano Campoy-Quiles,Luis Rodríguez-Fernández,Miquel Garriga,Maria Isabel Alonso +5 more
TL;DR: In this paper, the authors found that the sensitivity of the dimer FR signaltothevariation of the surface plasmon resonance (SPR) is 2 times larger than the region where nm < 1.5, which opens up the possibility of utilizing the FR band for more efficient optical sensing applications.
Journal ArticleDOI
Understanding the ion-induced elongation of silver nanoparticles embedded in silica
Ovidio Peña-Rodríguez,Alejandro Prada,José Olivares,Alicia Oliver,Luis Rodríguez-Fernández,H. G. Silva-Pereyra,Eduardo M. Bringa,José Manuel Perlado,Antonio Rivera +8 more
TL;DR: This work has studied the elongation of silver nanoparticles irradiated with 40 MeV Bromine ions by means of in situ optical measurements, transmission electron microscopy and molecular dynamics simulations, and the agreement is excellent in both cases.
Journal ArticleDOI
Linear optical response of metallic nanoshells in different dielectric media
TL;DR: In this paper, the surface plasmon resonance (SPR) of metal nanoshells has been studied for different geometries and physical environments, and the SPR peak position can be tuned from 510 nm (2.43 eV) to 660 nm (1.88 eV).
Journal ArticleDOI
AFM, XPS and RBS studies of the growth process of CdS thin films on ITO/glass substrates deposited using an ammonia-free chemical process
TL;DR: A detailed study of the growth stages of CdS thin films on ITO/glass substrates by chemical bath deposition was done through X-ray photoelectron spectroscopy (XPS), Rutherford backscattering spectrometry (RBS), and atomic force microscopy (AFM) techniques as mentioned in this paper.
