    • Ablation and optical third-order nonlinearities in Ag nanoparticles 

      Torres Torres, Carlos; Perea López, Néstor; Reyes Esqueda, Jorge Alejandro; Rodríguez Fernández, Luis; Crespo Sosa, Alejandro; Cheang Wong, Juan Carlos; Oliver G., Alicia (Dove Press Ltd, 2010)
      "The optical damage associated with high intensity laser excitation of silver nanoparticles (NPs) was studied. In order to investigate the mechanisms of optical nonlinearity of a nanocomposite and their relation with its ...

    • Identification of individual and few layers of WS2 using Raman Spectroscopy 

      Botello Méndez, Andrés Rafael; Perea López, Néstor; Elías Arriaga, Ana Laura; Vincent Crespi; López Urías, Florentino; Terrones Maldonado, Humberto; Terrones Maldonado, Mauricio (2013-04)
      "The Raman scattering of single-and few-layered WS2 is studied as a function of the number of S-W-S layers and the excitation wavelength in the visible range (488, 514 and 647 nm). For the three excitation wavelengths used ...

    • Near UV-blue excitable green-emitting nanocrystalline oxide 

      Rodríguez García, Carlos Eduardo; Perea López, Néstor; Hirata Flores, Gustavo Alonso (Hindawi, 2011)
      "Green-emitting Eu-activated powders were produced by a two-stage method consisting of pressure-assisted combustion synthesis and postannealing in ammonia. The as-synthesized powders exhibited a red photoluminescence (PL) ...

    • Pine-tree-like morphologies of nitrogen-doped carbon nanotubes: Electron field emission enhancement 

      García Betancourt, María Luisa; Perea López, Néstor; Vega Díaz, Sofía Magdalena; López Urías, Florentino; Elías Arriaga, Ana Laura; Ortiz Medina, Josué; Muñoz Sandoval, Emilio; Terrones Maldonado, Mauricio (2014)
      "Nitrogen-doped multiwalled carbon nanotube (CNT) bundles exhibiting pine-tree-like morphologies were synthesized on silicon-silicon oxide (Si/SiO2) substrates using a pressure-controlled chemical vapor deposition process. ...

    • 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)
