Fabricación y Caracterización de Sustratos Plasmónicos Basados en Nanobastones de Oro
Scarpettini, Alberto; Gutierrez, Marina (2015)Se fabricaron sustratos plasmónicos mediante el recubrimiento controlado de superficies de vidrio y películas delgadas de oro con nanobastones de oro. Estos sustratos nanoestructurados poseen resonancias ópticas en el ... -
Kinetic and plasmonic properties of gold nanorods adsorbed on glass substrates
Gutierrez, Marina; Scarpettini, Alberto F (2019-09-19)Monodisperse gold nanorods with different sizes were synthesized and adsorbed on chemically modified glass substrates. Influence of surfactant molar concentration on nanorod adsorption was studied and the optimum range was ... -
Monitoring the Photothermal Reshaping of Individual Plasmonic Nanorods with Coherent Mechanical Oscillations
Scarpettini, Alberto; Della Picca, Fabricio; Gutierrez, Marina; Bragas, Andrea (2018-12-03)Light absorption in gold nanoparticles leads to metal heating that induces photothermal reshaping because of atomic surface diffusion at temperatures well below the gold melting point. In this work, we perform time-resolved ... -
Nanorod-based plasmonic substrates with predefined optical resonances
Scarpettini, Alberto; Gutierrez, Marina (2018)To design and fabricate plasmonic substrates to be used in ultrasensitive chemical sensing or surfaceenhanced spectroscopies, it is important to achieve control on the morphology, dimensions and surface density of metallic ... -
Optical coherence tomography-based scanning system for shape determination, wall thickness mapping, and inner inspection of glass containers
Morel, Eneas Nicolás; Gutierrez, Marina; Miranda, Hernán; Sambrano, Edgardo; Torga, Jorge Román (2013-02)In this work we present a method that enables simultaneous measurement of shape and wall parameters of glass containers. The system is based on the optical coherence tomography technique, employing the spectral domain ... -
Recubrimiento controlado de sustratos de vidrio con nanobastones metálicos
Gutierrez, Marina; Paredes, María Yanela; Scarpettini, Alberto (2015-03-12)Se realizó la síntesis de nanobastones de oro monodispersos con una eficiencia superior al 80% sobre el total de nanopartículas, caracterizado por una resonancia plasmónica longitudinal cercana a los 800 nm. Se modi- ficaron ...
