Hot off the press: Published paper in The Journal of Physical Chemistry Letters

Congratulations to Anna Roig and the other co-autors for the paper: Ultrafast Synthesis and Coating of High-Quality β-NaYF4:Yb3+,Ln3+ Short Nanorods.
The paper was been published this November 2017 in The Journal of Physical Chemistry Letters! 

Abstract: An ultrafast route to prepare up-converting single β-phase NaYF4:Yb3+,Ln3+ (Ln: Er, Tm, or Tb) short nanorods (UCNRs) of high quality was developed. This new procedure affords reactive surface nanorods that are easily coated by direct injection of suitable capping ligands. Thus highly crystalline nanorods with excellent UC fluorescence and good solvent-selective dispersion are obtained, which represents a significant advance in the field and enlarges their use for biomedical and other technological applications. Unlike other methodologies, the short reaction time provides a kinetic control over crystallization processes, and the β-phase and rod morphology is preserved regardless of the optically active Ln3+ ion. The UC emission was finely tuned by using the most popular Yb3+/Tm3+ and Yb3+/Er3+ pairs. More importantly, UCNRs doped with the unusual Yb3+/Tb3+ pair, with no ladder-like energy levels, provided a nice emission upon near-infrared excitation, which constitutes the first example of phonon-assisted cooperative sensitization to date in pure β-NaYF4 nanocrystals.

Hot from the press: Two more published papers!

We congratulate two N&N researchers for two new publicationsMarti Gich for his third publication within a very short period of time and Anna Roig who is a co-author of one of the two recent publications. Both studies have been done together with other ICMAB researchers and collaborators from other institutions.
