Abstract

The novel flower-like WE₂ (E = S or Se) nanoflakes are synthesized and the growth of WS₂ and WSe₂ nanowires on stain less steel coupons (SSC) is observed by reaction under autogenic pressure at elevated temperature technique between the metallic tungsten and chalcogen powders at 750 °C for 3 h. Powder X-ray diffraction, scanning electron microscopy and transmission electron microscopy are used to characterize all reaction products, viz., neat WS₂, WSe₂ powder, WS₂/SSC and WSe₂/SSC (stainless steel coupon). The photoluminescence spectrum of WS₂ and WSe₂ samples are also reported. In addition, the direct use of metals as precursors will devoid the harmful effects of organometallic precursor.
