Volatile thorium amidates can be converted to ThO2 in the absence of an external oxygen source, and the thermal properties of these precursors can be readily tuned by modifying the ligand substituents.

AbstractThermolysis of single-source molecular precursors has been used to prepare carbon-supported Pt1Sn1, Pt1Ru1, and Pt3Mo1 alloy nanoparticles. On-particle, high spatial resolution energy dispersive spectroscopy (HR-EDS) has been used to determine the extent of compositional variability between particles in the nanocomposite. The loss of volatile Ru and Mo oxides during the course of the HR-EDS analysis results in average compositions greatly enriched in Pt. Mathematical correction for loss of these volatile species results in average metal:metal ratios comparable to those measured by bulk elemental analysis.

Background: Metal chalcogenide nanomaterials represent an important group of efficient materials, in which the subtle variations in shape, size and phase of nano-powders resulted in physical properties (e.g., electronic and optical) differing from their bulk counterparts, which makes them useful materials for various technological devices. Objective: Synthesis and growth of chalcogenide nano powders from novel single source molecular precursors (i.e., Cd(II) bis-(aminopropane) selenide, Cd(II) bis-(aminoethane) telluride) for the production of cadmium chalcogenide (CdE, E= Se/Te) at nano scale. Method: Single source molecular precursor inserted in quinoline, acting as a coordinating solvent at suitable temperature, yielded vacuum dried powders of CdSe and CdTe nanomaterials. Results: The average particle size was estimated as CdSe ≈ 3 nm, and CdTe ≈ 29 nm from powder X-ray diffraction pattern of synthesized nanoparticles. The produced nanomaterials possess optical properties and calculated energy band gap of nanoparticles as CdTe = 5.2 eV and CdSe = 4.0 eV from UV-Visible spectra. Conclusion: The economical, harmless single source molecular method may be a striking technique to fabricate metal chalcogenide nanoparticles.
