The novel flower-like WE 2 (E = S or Se) nanoflakes are synthesized and the growth of WS 2 and WSe 2 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 WS 2 , WSe 2 powder, WS 2 /SSC and WSe 2 /SSC (stainless steel coupon). The photoluminescence spectrum of WS 2 and WSe 2 samples are also reported. In addition, the direct use of metals as precursors will devoid the harmful effects of organometallic precursor.
