    • Development of nanocrystal based light sources in silicon 

      Juvert Sández, Joan (Universitat Politècnica de Catalunya, 2009-09-09)
      Projecte Final de Màster Oficial
      Accés obert
      In the present work we have fabricated capacitors with silicon nanocrystals embedded in a dielectric matrix. All the techniques used in the fabrication process are fully compatible with CMOS technology. We will show the ...

    • Estudi de la fenomenologia d'emisió de llum durant la fractura de materials compostos 

      Puga Rabassó, Francisco de Borja (Universitat Politècnica de Catalunya, 2017-05)
      Treball Final de Grau
      Accés restringit per decisió de l'autor
      L’estudi a continuació tracta sobre la fenomenologia que causa l’aparició d’un feix de llum en el moment de la fractura de materials compostos, concretament materials amb una matriu polimèrica i un reforç de fibra de vidre. ...

    • Solution-growth and optoelectronic properties of ZnO:Cl@ZnS core-shell nanowires with tunable shell thickness 

      Fan, Jiandong; Fábrega, Cristian; Zamani, Reza; Shavel, Alexey; Güell, Frank; Carrete, Alex; Andreu, Teresa; López Martínez, Antonio Miguel; Morante Lleonart, Joan Ramon; Arbiol, Jordi; Cabota, Andreu (2013-04-05)
      Article
      Accés restringit per política de l'editorial
      Arrays of vertically aligned ZnO:Cl@ZnS core–shell nanowires (NWs) were grown by a facile low-cost, high-yield and seed-free two-step process. These NWs were used to demonstrate the potential of 3D electrodes based on ...

    • Study of the effect of the chromophore and nuclearity on the aggregation and potential biological activity of gold(I) alkynyl complexes 

      Gavara, Raquel; Aguilo, Elisabet; Schur, Julia; Llorca Piqué, Jordi; Ott, Ingo; Rodríguez Raurell, Laura (2016-05-01)
      Article
      Accés obert
      The synthesis and characterization of four organometallic gold(I) complexes containing different water soluble phosphanes (TPPTS, PTA and DAPTA) and chromophoric units (4-pyridylethynyl and propargyloxycoumarin) is here ...

    • Ultrafast multi-photon excitation of ScVO4:Bi3+ for luminescence thermometry 

      Escofet Martín, David; Ojo, Anthony; Peterson, Brian (2022-01-01)
      Article
      Accés obert
      We demonstrate a multi-photon excitation (MPE) scheme for luminescence thermometry using ScVO4:Bi3+. MPE is performed using a 37 fs Ti:sapphire laser pulse centered at 800 nm. Log-log plots of the phosphorescence intensity ...

    • Up-conversion luminescence coupled to plasmonic gold nanorods for light harvesting and hydrogen production 

      AlGhamdi, H.; Katsiev, K.; Wahab, A.K.; Llorca Piqué, Jordi; Idriss, Hicham (2017-11-07)
      Article
      Accés obert
      The conversion of infrared light to visible-light which allows a larger fraction of sun-light to be used is needed to improve light-harvesting. In this work a tri-functional material composed of an up-converter (NaYF4–Yb–Tm), ...
