Metal sulfide WS2 nano-films synthesis and characterization : A focus on cost and mechanical properties enhancement

K.M.Boubaker

WS2 nano films have been elaborated from WO3 layers grown on glass substrates using a simple and cheap technique. Several characterization means including classical and original protocols, like Vickers micro-hardness test and Amlouk-Boubaker opto-thermal expansivity AB analyses have been carried out. The results showed that the finally fabricated films contained only WS2. This feature gives a meaningful advantage to the process in the matter of product purity, as long as similar ones yielded undesirable products such as WOyS2-y and WOyS2.
