181. Colloidal metal nanoparticles as a source for the growth of thin filmsSaim Emin, 2022, objavljeni povzetek znanstvenega prispevka na konferenci (vabljeno predavanje) Opis: Synthesis of colloidal nanoparticles (NPs) which offer good colloidal stability is quite important for different applications like spin-coating, dip-coating etc. Having metallic nanoparticles in the form of stable suspension allow the generation of thin films with desired thicknesses. We will present the production of different classes of materials starting from colloidal metal NPs. An example will be given on the preparation of Fe2O3 and WO3 thin films which are used in photoelectrochemical oxidation of water (e.g. water splitting). Another transformation which involves metallic NPs include the preparation of MoSe2 and WSe2 thin films which is achieved in a tube furnace at elevated temperatures. Very recently, the use of metallic NPs were also extended for the preparation of transition metal carbides. We managed to produce W2C and WC phases starting from metallic W NPs. The details of this phase conversion will be discussed. The presentation will provide details on how transition metallic NPs can be used to prepare metal oxide, metal selenide and metal carbides.
