Bi2S3 Nanowires, Rods and Fabric

Orthorhombic 81283 (bismuthinite) via a solventiess method can yield either high aspect ratio ( 100) nanowires at about 225 °C (Fig. 20.3 a) or lower aspect ratio ( 7) (plus sulfur which seems to change the growth kinetics) at around 160 °C. Interestingly, it is possible to fabricate a polymeric matrix from these wires and rods at higher temperatures, 250°C, as shown in Fig. 20.3b [6]. 

A non-thiol precursor, a solid lead chloride-octanoate complex, produces mendi-pite nanobelts after being heated in air for 1 h at 190 °C (Fig. 20.4). A remark-
