Carmona Tejero, Noemi ; Bouzas, V. ; Jiménez, F. ; Plaza, M. ; Pérez García, Lucas ; García, M. A. ; Villegas, M. A. ; LLopis, J. | Elsevier Science S A | 2010-03-04Optical absorption and magnetic properties of silica sol-gel monoliths doped with cobalt starting from different precursors and water/1-propanol molar ratios are investigated. Structural characterization of the sol-gel by X-ray absorption near-e[...]texto impreso
Gálvez Alonso, Fernando ; Monton, C. ; Serrano, A., A. ; Valmianski, I. ; De la Venta, J. ; Schuller, Ivan K. ; García, M. A. | Elsevier Science S A | 2012-09We study the effect of photodiode angular response on the measurement of surface plasmon resonance (SPR) in metallic thin films using the Kretschmann-Raether configuration. The photodiode signal depends not only on the light intensity but also o[...]texto impreso
Díaz Herrera, Natalia ; Viegas, Diana Catarino das Neves ; Jorge, Pedro A. S. ; Araújo, Francisco Manuel Moita ; Santos, Jose Luis ; Navarrete Fernández, María Cruz ; González Cano, Agustín | Elsevier Science S A | 2010-01-29In this work a new configuration of a refractometric sensor for aqueous solutions based on the combination of surface plasmon resonance (SPR) with fibre Bragg gratings (FBG) is presented. Two FBGs are selected having reflection maxima in each si[...]texto impreso
Gálvez Alonso, Fernando ; Pérez de Lara, D. ; Spottorno Giner, Jorge ; García, M. A. ; Vicent López, José Luis | Elsevier Science S A | 2017-05We present here a study of the possible local heating effects in surface plasmon resonance sensors using low power lasers (?mW/mm_2). By measuring the increase of electrical resistivity in an Au stripe while exciting SPR and performing numerical[...]texto impreso
Esteban Martínez, Óscar ; Díaz Herrera, Natalia ; Naranjo Vega, Fernando Bernabé ; Valdueza Felip, Sirona ; Navarrete Fernández, María Cruz ; González Cano, Agustín | Elsevier Science S A | 2011-11-15In this work, an Indium Nitride (InN) dielectric overlay has been used to develop a surface plasmon resonance optical fiber sensor. Although InN is a very promising material in electronics industry, this is the first time that this kind of mater[...]texto impreso
Rodriguez Schwendtner, E. ; Navarrete Fernández, María Cruz ; Díaz Herrera, Natalia ; Esteban Martínez, Óscar ; González Cano, Agustín | Elsevier Science S A | 2016-02We present a new technique for exciting and collecting fluorescence with all-fiber devices, consisting of two different tapered fibers, a microfiber used as illuminating source and a polymer optical fiber where a fluorophore has been deposited a[...]texto impreso
Navarrete Fernández, María Cruz ; Díaz Herrera, Natalia ; González Cano, Agustín ; Esteban Martínez, Óscar ; Leite, Ivo | Elsevier Science S A | 2011-12-15Conventional surface plasmon resonance (SPR) fiber sensors show selective behavior when resonance wavelengths are tuned to absorption peaks of the surrounding medium, as it is experimentally shown and evaluated in this paper by using a doubly-de[...]texto impreso
Navarrete Fernández, María Cruz ; Díaz Herrera, Natalia ; González Cano, Agustín ; Esteban Martínez, Óscar | Elsevier Science S A | 2014-01Doubly deposited uniform-waist tapered optical fibers (DLUWTs) have shown their versatility and good performance as basis for surface plasmon resonance (SPR) sensors for a variety of wavelength ranges. In this work we experimentally show how the[...]
