| Popis | Synthesis of tellurium-based materials via chemical synthesis is usually based on the reduction of the tellurium source (for example Na2TeO3 or TeCl4) [1] together with (semi) metallic source (GeI2 or SnCl2) [2] at the elevated temperatures (above 150 degrees C) for several hours. There are also reports showing that similar procedure in the presence of second metallic source (for example InCl3, In(NO3)(3)) or even the metallic nanoparticles (NPs) may provide doped telluride materials [3]. The presence of NPs with various diameters gives the possibility to control the dimensions of nanostructures of tellurium-based materials [4]. Nanoparticles can offer an alternative approach to fabricate phase change materials. Contrary, the reports of chemical synthesis at room temperatures are in fact unknown. The aim of this work is preparation of GeTe nanoparticles by low temperature synthetic method exploiting new organometallic precursors. The characterization of prepared nanomaterial was performed on the basis of X-ray diffraction, transmission electron microscopy, scanning electron microscopy (SEM) with energy dispersive X-ray (EDX) spectroscopy, laser ablation time-of-flight (LA TOF) mass spectrometry (MS), Raman scattering spectroscopy and dynamic light scattering. |
