Serrano, A. ; Llorca Hernando, O. ; Campo, A. del ; Rubio Marcos, F. ; Rodríguez de la Fuente, Óscar ; Fernandez, J. F. ; García, M. A. | Amer Inst Physics | 2018-10-07We present here a study on the modification of morphological and plasmonic properties of Ag thin films deposited on glass substrates upon annealing in air at different temperatures. Initially, Ag films are continuous and exhibit extended surface[...]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

Guerrero, E. ; Rojas, T. C ; Multigner, M. ; Crespo del Arco, Patricia ; Muñoz Márquez, M. A. ; García, M. A. ; Hernando Grande, Antonio ; Fernández, A. | Pergamon-Elsevier Science Ltd | 2007-03In the present paper, we show an exhaustive microstructural characterization of thiol-capped gold nanoparticles (NPs) with two different average particle sizes. These samples are compared with the polymer-like Au(I) phase formed as a precursor d[...]texto impreso
Gálvez Alonso, Fernando ; Pérez de Lara, D. ; García, M. A. ; Vicent López, José Luis | Elsevier Sci. Ltd | 2017-12We present here an experimental set-up system to excite and measure simultaneously surface plasmon resonance (SPR) and magneto-optic signal in hybrid magneto-plasmonic systems using two independent light sources. The system can be used to excite[...]texto impreso
