Temperature-Dependent Emission of Monolayer-Protected Au38 Clusters

Autor: van Wijngaarden, J.T., Toikkanen, O., Liljeroth, P., Quinn, B.M., Meijerink, A., Condensed Matter and Interfaces, Sub Condensed Matter and Interfaces

Publikováno v: Journal of Physical Chemistry C, 114, 16025. American Chemical Society

Emission spectra are presented for Au38 clusters in the temperature regime between 4 and 300 K. At room temperature, a broad emission band around 1.35 eV is observed. Upon cooling, fine structure appears that reveals the presence of at least four emi

Quantised charging of monolayer-protected nanoparticles

Autor: Laaksonen, T., Ruiz, V., Liljeroth, P.W., Quinn, B.M.

Metal nanoparticles coated with an organic monolayer, so-called monolayer protected clusters (MPCs), can show quantised charging at room temperature due to their sub-attofarad capacitance arising from the core size and the nature of the protecting mo

Ion limited charging of nanoparticle thin films

Autor: Laaksonen, T., Ruiz, V., Liljeroth, P.W., Quinn, B.M.

This article reports on the charging behavior of thin films of alkanethiol protected gold nanoparticles, socalled monolayer protected clusters (MPCs), immersed in aqueous solution. We demonstrate that the oxidation of the MPCs is controlled by the tr

Synthesis and stability of monolayer-protected Au38 clusters

Autor: Toikkanen, O., Ruiz, V., Rönnholm, G., Kalkkinen, N., Liljeroth, P.W., Quinn, B.M., Chemie van de vaste stof: Luminescentie en elektrochemie, Dep Scheikunde

Publikováno v: Journal of the American Chemical Society, 130(33), 11049. American Chemical Society

A synthesis strategy to obtain monodisperse hexanethiolate-protected Au38 clusters based on their resistance to etching upon exposure to a hyperexcess of thiol is reported. The reduction time in the standard Brust−Schiffrin two-phase synthesis was

Electrochemical gating in scanning electrochemical microscopy

Autor: Ahonen, P., Ruiz, V., Kontturi, K., Liljeroth, P., Quinn, B.M., Chemie van de vaste stof: Luminescentie en elektrochemie, Dep Scheikunde

Publikováno v: Journal of Physical Chemistry C, 2724. American Chemical Society
STARTPAGE=2724;ISSN=1932-7447;TITLE=Journal of Physical Chemistry C

We demonstrate that scanning electrochemical microscopy (SECM) can be used to determine the conductivity of nanoparticle assemblies as a function of assembly potential. In contrast to conventional electron transport measurements, this method is uniqu
