Thermal decomposition of four single-source precursors of the type (Et sub(2)Sb) sub(2)E and Et sub(3)SbE (E = S, Se) at 170 degree C in the presence of suitable capping agents yielded binary Sb sub(2)S sub(3) and Sb sub(2)Se sub(3) nanowires. In addition, simultaneous decomposition of (Et sub(2)Sb) sub(2)S and(Et sub(2)Sb) sub(2)Se gave the ternary phase Sb sub(2)(S,Se) sub(3) with almost equal S and Se concentrations. The materials were characterized by XRD, REM, EDX, ED and HRTEM. Binary Sb sub(2)S sub(3) and Sb sub(2)Se sub(3) nanowires as well as ternary Sb sub(2)(S,Se) sub(3) nanowires were synthesized by thermal decomposition of four novel single-source precursors of the type (Et sub(2)Sb) sub(2)E and Et sub(3)SbE (E = S, Se) in the presence of suitable capping agents and characterized by XRD, REM, EDX, ED and HRTEM.
