eng	New low temperature synthetic method for preparation of tellurides nanoparticles	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 °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 films of phase change material. Contrary, the reports of chemical synthesis at room temperatures are in fact unknown. The aim of this work is preparation of tellurides nanoparticles of main group metals by low temperature synthetic method by the help new organometallic precursors. The main part will be focused on different preparation methods and characterization GeTe nanoparticles. The characterization of prepared nanomaterial was performed on the basis of high-temperature X-ray diffraction, transmission electron microscopy, LA TOF mass spectrometry, X-ray diffraction, Raman spectroscopy and dynamic light scattering.
