Abstract

WS 2 nanotubes (NTs) are layered transition‐metal dichalcogenides whose diameter strongly influences strain and optical properties. Alloying sulfur with selenium in W(S x Se 1− x ) 2 NTs provides compositional tunability, yet the link between precursor composition, alloy formation, and optical response remains unclear. In this work, W(S x Se 1− x ) 2 (WSSe) NTs with controlled S/Se ratios were synthesized and characterized using Raman spectroscopy, scanning electron microscopy, transmission electron microscopy, STEM‐EDS, and X‐ray diffraction. The synthesis produced high yields of small‐diameter NTs (
