Figure 2

Scanning electron micrographs of WO3nano-rods grown under oxygen as a central carrier gas and C2H2as the secondary carrier gas showing a thin film that has flaked up into orderly slabs between which are numerous nano-wires. Inset (a) shows a close look at the nano-wires in between the slabs. Inset (b) zooms in onto the nano-wire area and inset (c) display one nano-wire’s end
