Dimeric Complexes of Lanthanide(III) Hexafluoroacetylacetonates with 4-Cyanopyridine N-Oxide: Syn thesis, Crystal Structure, Magnetic and Photoluminescent Properties

Jean-Claude Bünzli, Frédéric Gumy, Svetlana Eliseeva

A series of new mixed-ligand lanthanide complexes [Ln(hfa)3(4-cpyNO)]2 (Ln = SmIII-HoIII and TmIII; hfa- = hexafluoroacetylacetonate; 4-cpyNO = 4-cyanopyridine N-oxide) have been synthesised by treating the corresponding lanthanide hexafluoroacetylacetonat ...

Enantiopure helical (supra)molecular arrays containing lanthanides

Marco Antonio Lama

The diastereoselective synthesis of chiral coordination compounds with d metals proved the effectiveness of the pinene-bipyridine approach in predetermining the chirality at the metal centre. The strong Lewis acidic character of lanthanide cations required ...

Ferroelectric and piezoelectric properties of lanthanoid-substituted Bi4Ti3O12 thin films grown on (111)Pt and (100)IrO2 electrodes

Nava Setter, Paul Muralt

We investigated he effect of film orientation on piezoelectric and ferroelectric properties of (Bi(3.25)Ln(0.75))Ti3O12 (Ln=La, Nd, and Sm). c-axis-oriented films were grown on (111)Pt electrodes with nondoped Bi4Ti3O12 buffer layers. The films grown on (1 ...

Gold nano-antennas for increasing luminescence

Philippe Gillet

Energy transfer between nanoscale particles is demonstrated for a Gold/rare-earth oxide nanocomposite. The gold nanoparticle acts as an antenna, absorbing light that can then be transferred to the bound rare-earth oxide (see Figure), enhancing the oxide lu ...

Precipitation and transformation of nanostructured copper oxalate and copper/cobalt composite precursor synthesis

Lucica Soare

The aim of this thesis was to synthesise and control a nanostructured composite of copper/cobalt. Both the copper and cobalt oxalate exhibit a nanostructure. Attempts to produce nanocomposite particles in the size range of 10-70 nm were made via an oxalate ...

Microstructural evolution of Y2O3 and MgAl 2O4 ODS EUROFER steels during their elaboration by mechanical milling and hot isostatic pressing

Cyril Cayron

Different ODS EUROFER steels reinforced with Y2O3 and MgAl2O4 were elaborated by mechanical milling and hot isostatic pressing. Good compromise between strength and ductility could be obtained but the impact properties remain low (especially for the Y 2O3 ...

Specific heat capacity and Debye temperature of zirconia and its solid solution

Manuel Alexandre Pouchon

Specific heat CP of zirconia and yttria stabilized zirconia doped or not with erbia and ceria was measured from 128 to 823 K and of yttria stabilized zirconia doped with erbia and plutonia from 443 to 1573 K. The new determined data were modelled using Deb ...

A Highly Stable Gadolinium Complex with a Fast, Associative Mechanism of Water Exchange

André Merbach, Lothar Helm, Gaëlle Nicolle

The stability and water exchange dynamics of gadolinium (GdIII) complexes are critical characteristics that determine their effectiveness as contrast agents for magnetic resonance imaging (MRI). A new heteropodal GdIII chelate, [Gd-TREN-bis(6-Me-HOPO)-(TAM ...

High-Power Nd-Doped Fiber Amplifier for Coherent Intersatellite Links

René Dändliker

Intersatellite optical communication links require laser beams of at least 1 W of power modulated at gigahertz frequencies. They can be delivered by a master oscillator power amplifier system which consists of a stable single-frequency Nd:YAG laser, a high ...

Stable picosecond pulse generation at 1.3 µm in a Pr3+-doped all-fiber laser actively mode-locked using a novel fiber-optic phase modulator

René Salathé, Hans Georg Limberger

Rare-earth doped fibers can be used to realize simple, compact sources of ultrashort pulses. To date, considerable effort has been developed to obtain short pulse generation in Er3+-doped fiber lasers at 1.55 µm. Contrary to this, little work has bee ...
