Abstract EN
The Ag-Cu bimetallic colloidal nanoparticles (NPs) were prepared by solvothermal synthesis from metalloorganic precursors in a mixture of organic solvents.
The nanoparticles were characterized by dynamic light scattering (DLS) and small angle X-ray scattering (SAXS).
The properties of metallic core and organic shell of the nanoparticles were studied by direct inlet probe mass spectrometry (DIP/MS), Knudsen effusion mass spectrometry (KEMS), double-pulse laser-induced breakdown spectroscopy (DPLIBS), and differential scanning calorimetry (DSC).
The transmission electron microscopy (TEM) and scanning electron microscopy (SEM) were used for particle characterization before and after thermal analysis.
The experiment yielded results that were for AgCu nanoparticles for the first time.
The detected liquidus temperature has been compared with the prediction obtained from calculation of the phase diagram of Ag-Cu nanoalloy.
The experimental results show that of near-eutectic composition AgCu nanoparticles possess the fcc crystal lattice.
Surprisingly, spinodal decomposition was not observed inside the AgCu nanoparticles at temperatures up to 230°C.
The depression of the eutectic AgCu melting point was calculated but not observed.
The eutectic AgCu microparticles are formed before melting.
