Diffuse reflectance spectroscopy characterization of molecular absorption via graphene based photodetectors
(Universitat Politècnica de Catalunya, 2018-09)
Master thesis
Restricted access - confidentiality agreementThis 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 ... -

Narrowband filtering for atom-resonant photon pair generation
(Universitat Politècnica de Catalunya, 2017-10-27)
Master thesis
Open AccessIn 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
(Universitat Politècnica de Catalunya, 2018-10-24)
Master thesis
Open Access
Covenantee: Bundesanstalt für Materialforschung und -prüfungThe 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
(Universitat Politècnica de Catalunya, 2018-09-06)
Master thesis
Open AccessThe 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
(2015-01-08)
Article
Open AccessImpedance 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 ...
