    • Attosecond x - ray transient dynamics 

      Delgado Guerrero, Jorge (Universitat Politècnica de Catalunya, 2017-09-08)
      Projecte Final de Màster Oficial
      Accés obert

    • Diffuse reflectance spectroscopy characterization of molecular absorption via graphene based photodetectors 

      Evans, Michael (Universitat Politècnica de Catalunya, 2018-09)
      Projecte Final de Màster Oficial
      Accés obert
      This Master dissertation explores diffuse reflection spectroscopy as a viable tool for analytical chemistry, both quantitatively and qualitatively. In-vitro optical phantoms are created to mimic the turbid diffuse environments ...

      Accés restringit per acord de confidencialitat

    • Narrowband filtering for atom-resonant photon pair generation 

      Torrent Cuairan, Marc (Universitat Politècnica de Catalunya, 2017-10-27)
      Projecte Final de Màster Oficial
      Accés obert
      In this master's thesis we study two filtering techniques, first the Faraday anomalous dispersion optical filter (FADOF) and second a monolithic Fabry-Pérot interferometer with the aim of filtering down-converted photon ...

    • Spectroscopic characterization of Er3+, Yb3+ co-doped UC single crystals : the influence of host and sensitizer concentrations 

      Saleta Reig, David (Universitat Politècnica de Catalunya, 2018-10-24)
      Projecte Final de Màster Oficial
      Accés obert
      Realitzat a/amb:   Bundesanstalt für Materialforschung und -prüfung
      The energy transfer upconversion (ETU) mechanism is known to be the most efficient route for the conversion of near infrared (NIR) light to visible emission in Ln3+-co-doped systems. In this work, we examined these energy ...

    • Towards cavity enhanced detection of single ions in the solid-state 

      Van Valkenhoef, Céline Hélène Ida (Universitat Politècnica de Catalunya, 2018-09-06)
      Projecte Final de Màster Oficial
      Accés obert
      The goal of this master thesis was to take initial steps towards cavity-enhanced detection of single rare-earth ions in the solid state. A fibre microcavity set-up for use with Praseodymium-doped nanocrystals was designed, ...

    • Water-Triggered Conduction Mediated by Proton Exchange in a Hygroscopic Fulleride and Its Hydrate 

      Zachariah, Manesh; Mitsari, Efstratia; Romanini, Michela; Zygouri, Panagiota; Gournis, Dimitrios; Barrio Casado, María del; Tamarit Mur, José Luis; Macovez, Roberto (2015-01-08)
      Article
      Accés obert
      Impedance spectroscopy is employed to probe the impact of water on the dc conductivity and ac dielectric response of the polycrystalline C-60(ONa)(24) fulleride, both in its bulk-hydrate form, stable only below 370 K, and ...
