In this article, a simple and reproducible technique for the synthesis of silver nanoparticles in organic phase without using external reducing agents is reported. The organic phase contains silver acetate as precursor, oleic acid and oleyl amine as capping molecules and diphenyl ether as solvent. Monodispersed silver nanoparticles with an average size of 5 nm could be easily synthesised at large scale and it was possible to isolate the particles suitable for electronics applications. The formation of silver nanoparticles has been characterised in terms of optical absorption, transmission electron microscopy images and smallangle X-ray scattering. Recovered silver nanoparticles reveal X-ray diffraction of a well grown-up fcc-Ag lattice. Chemical and thermal characterisations of silver nanopowders were carried out using X-ray photoelectron spectroscopy and thermogravimetric analysis, respectively. For the latter purpose, concentrated dispersions of silver nanoparticles were prepared and used for depositing uniform thin layers. Thin films were sintered at low temperature to obtain conductive films and the films were characterised using scanning electron microscope. Electrical conductivity of the conductive films was in the range 2-3 Â 10 4 S cm À1 .

“…PVA has a low decomposition temperature so that elimination of PVA from the obtained electrospun nano-fibre mats is an easy task. [39] Likewise, silver acetate decomposes easily by heat. [40] Accordingly, one can say that at the aforementioned calcination temperatures PVA has been completely eliminated and silver acetate decomposed into silver.…”

In this study, we have introduced electrospinning of a colloidal solution rather than the conventional sol-gel process as a novel strategy to produce silver nanofibres. Typically, a silver acetate/polyvinyl alcohol colloidal solution was successfully electrospun. Electrophoretic light scattering (ELS) and dynamic light scattering (DLS) analyses have affirmed that the electrospun solution is a colloid with a ζ-potential of -2 mV and average particle diameter of 373 Ϯ 1 nm. Moreover, FTIR analysis affirmed that neither the polymer nor silver acetate

“…Decomposition of Au [27], Ni [28] and Ag acetates [29] in an inert atmosphere leads to the formation of metallic nanoparticles, whereas oxidation of Ce(III) into Ce(IV) is usually observed for ceria precursors even in an inert atmosphere [19]. The effect of oxidizing or reducing species produced during decomposition or coming from the furnace atmosphere will depend, in general, on their transport across the sample.…”

Thermal analysis of metal organic precursors for functional oxide preparation: Thin films versus powders

et al. 2015

The thermal decomposition of several metal organic precursors, used in the preparation of YBa 2 Cu 3 O 7-x superconducting coated conductors (Cu acetate, Cu, Y and Ba trifluoroacetates and Ce propionate) is analyzed by means of several thermoanalytical techniques (TG/DTA, MS and DSC). In all cases, the metal organic precursors deposited as thin films decompose differently than powders from the same precursors. In thin films, decomposition is facilitated by the easier transport of reactive gas from the surrounding atmosphere and by the easier out-diffusion of volatile products. Consequently, films decompose at lower temperature and are more sensitive to the presence of any residual reactive gas in the furnace. Good thermal contact with the substrate is also shown to minimize overheating in films and avoid combustion processes that are otherwise often observed during the thermal decomposition of powders. Finally, the formation and stability of intermediate products towards the oxide formation, such as metal fluorides, differs in films because of the easier gas exchange. With respect to powders, these compounds are much less stable in films, where their decomposition temperature can be lowered by several hundreds of degrees Celsius. While in some cases the behaviour of films can be predicted by analyzing varying masses of precursor powders, this is not always the case. Therefore, thermal analysis carried out on films is recommended to avoid erroneous conclusions about materials preparation drawn from powders.
