Coexistence of two-photon absorption and saturable absorption in ion-implanted platinum nanoparticles in silica plates
Torres Torres, Carlos; Bornacelli, J.; Can-Uc, Bonifacio Alejandro; Silva Pereyra, Héctor Gabriel; Rodríguez Fernández, Luis; Ávalos Borja, Miguel; Labrada Delgado, Gladis Judith; Cheang Wong, Juan Carlos; Rangel Rojo, Raúl; Oliver y Gutiérrez, Alicia María (Optical Society of America, 2018)"Platinum nanoparticles were nucleated in a high-purity silica matrix by an ion-implantation method. The third-order nonlinear optical response of the samples was studied using femtosecond pulses at 800 nm with the z-scan ... -
Compressibility, microcalorimetry, elastic properties and EELS of rhenium borides
Neun, Christopher; Petermüller, Benedikt; Bayarjargal, Lkhamsuren; Morgenroth, Wolfgang; Ávalos Borja, Miguel; Silva Pereyra, Héctor Gabriel; Spahr, Dominik; Schmuck, Felix; Milman, Victor; Huppertz, Hubert; Winkler, Bjoern (Elsevier, 2018)"Based on synchrotron X-ray diffraction on phase-pure samples, we revised the bulk moduli of the rhenium borides Re7B3 (B-0 (Re7B3) = 391(5) GPa) and orthorhombic Re3B (B-0 (orthorhombic Re3B) = 393(4) GPa) and determined ... -
Platinum nanoclusters in silica: Photoluminescent properties and their application for enhancing the emission of silicon nanocrystals in an integrated configuration
Bornacelli, J.; Silva Pereyra, Héctor Gabriel; Rodríguez Fernández, Luis; Ávalos Borja, Miguel; Oliver G., Alicia (2016-09)"We studied photoluminescence of ion implanted platinum nanoclusters embedded in silica. Pt ions were implanted at 2 MeV and the Pt nanoclusters were then nucleated by thermal treatment under either argon, air, or a reducing ... -
Superlinear photoluminescence by ultrafast laser pulses in dielectric matrices with metal nanoclusters
Bornacelli, J.; Torres Torres, Carlos; Silva Pereyra, Héctor Gabriel; Labrada Delgado, Gladis Judith; Crespo Sosa, Alejandro; Cheang Wong, Juan Carlos; Oliver y Gutiérrez, Alicia María (Nature Publishing Group, 2019)"An intense photoluminescence emission was observed from noble metal nanoclusters (Pt, Ag or Au) embedded in sapphire plates, nucleated by MeV ion-implantation and assisted by an annealing process. In particular, the ... -
Synthesis, characterization and magnetic properties of Co@Au core-shell nanoparticles encapsulated by nitrogen-doped multiwall carbon nanotubes
Muñoz Sandoval, Emilio; Perea López, Néstor; Lima Juárez, Rodolfo; Labrada Delgado, Gladis Judith; Rivera Escoto, Beatriz Adriana; Zamudio Ojeda, Adalberto; Silva Pereyra, Héctor Gabriel; Robles Avila, Emmanuel; Terrones Maldonado, Mauricio (2014)"Co/Au bilayer thin films were deposited on Si/SiOx substrates using the magnetron sputtering method and used as a catalytic support to grow forests of aligned nitrogen-doped multiwalled carbon nanotubes (N-MWCNT) via ... -
Understanding the ion-induced elongation of silver nanoparticles embedded in silica
Peña Rodríguez, Ovidio; Prada, Alejandro; Olivares, José; Oliver G., Alicia; Rodríguez Fernández, Luis; Silva Pereyra, Héctor Gabriel; Bringa, Eduardo M.; Perlado, José Manuel; Rivera, Antonio (2017-04)"In this work we have 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.
