Interfacial structure in silicon nitride sintered with lanthanide oxide
Three independent research groups present a comparison of their structural analyses of prismatic interfaces in silicon nitride densified with the aid of lanthanide oxide Ln2O3. All three groups obtained scanning transmission electron microscope images which clearly reveal the presence of well-defined Ln segregation sites at the interfaces, and, moreover, reveal that these segregation sites are ...
متن کاملMulticolor tuning of lanthanide-doped nanoparticles by single wavelength excitation.
Lanthanide-doped nanoparticles exhibit unique luminescent properties, including large Stokes shift, sharp emission bandwidth, high resistance to optical blinking, and photobleaching, as well as the unique ability to convert long-wavelength stimulation into short-wavelength emission. These attributes are particularly needed for developing luminescent labels as alternatives to organic fluorophore...
متن کاملFine-tuning of lanthanide-monocarboxylate coordination networks through ligand decoration.
We report herein five new coordination polymers of general formula [LnNa(C(6)H(5)CO(2))(4)] where Ln = Y (6), Tb (7), Er (8), [DyNa(CH(3)CO(2))(4)(MeOH)] (9) and [DyNa(C(3)H(7)CO(2))(4)] (10). Single crystal structure analyses revealed that all compounds have a repeating unit containing one Ln(3+), one Na(+) and four monocarboxylate ligands (RCO(2)(-)) (R = -CH(3), -C(3)H(7), -C(6)H(5)). Compou...
متن کاملLanthanide-doped LiYF4 nanoparticles: Synthesis and multicolor upconversion tuning
We report the synthesis of tetragonal-phase LiYF4 nanoparticles doped with upconverting lanthanide ions. The nanoparticles have been characterized by XRD, TEM, and luminescence decay studies. The size of the as-synthesized LiYF4 nanoparticles can be tuned by varying the precursor ratio of F to lanthanide ions. Passivated by oleic acid ligands, the LiYF4 nanoparticles can be readily dispersed in...
متن کاملMagnetic susceptibilities of chromites from Oman
MINERALOGICAL and physical characteristics of natural chromites from Oman ophiolites have been recently investigated using M6ssbauer spectrocopy (MS), X-ray diffraction (XRD) and Scanning electron microscopy (SEM) by Al-Alawi et al. (1996). From the MS analysis together with the SEM data, they derived the chemical formula for specimens collected from two separate chromite deposits named Tawiyah...
