Electrically driven phase transition inmagnetite nanostructurers
(NATURE PUBLISHING GROUP, 2008-02)Magnetite (Fe3O4), an archetypal transition-metal oxide, has been used for thousands of years, from lodestones in primitive compasses(1) to a candidate material for magnetoelectronic devices(2). In 1939, Verwey(3) found ... -
Enhanced coupling of electronic and photonic states in a microcavity-quantum dot system
(2005)Spherical microcavities consisting of a dielectric material show unique optical characteristics as resonators in combination with semiconductor nanoparticles. A high quality factor results in a very narrow bandwidth of the ... -
Experimental and Theoretical Investigation of the Distance Dependence of Localized Surface Plasmon Coupled Forster Resonance Energy Transfer
(2014)The distance dependence of localized surface plasmon (LSP) coupled Förster resonance energy transfer (FRET) is experimentally and theoretically investigated using a trilayer structure composed of separated monolayers of ... -
Modification of photon states in photonic molecules with semiconductor nanocrystals
(Springer, 2005)We report on the coherent coupling of whispering gallery modes (WGM) in a photonic molecule formed from two melamine-formaldehyde spherical microcavities coated with a thin shell of CdTe nanocrystals (NCs). Utilizing ... -
Size selective photoluminescence excitation spectroscopy in CdTe quantum dots
(2003)We present a photoluminescence and photoluminescence excitation study of CdTe quantum dots, prepared via a novel organometallic approach. The global photoluminescence (excited at the energy above the absorption edge) ... -
An XPS Study of the Oxidation of Reduced Ceria-Lanthana Nanocrystals
(Elsevier, 2011)Detailed x-ray photoelectron spectroscopy (XPS) studies on the oxidation of an extensivley cleaned, reduced ceria-lanthana solid solution (12.5 mol% La to Ce) was performed. Uptake of oxygen during oxidation followed a ...
