Figure 6

Left: the Raman spectrum of the sample prepared at the 10.6-μm wavelength and 85 W/cm 2 power density with a SEM micrograph in the inset showing the morphology. Right: the corresponding XRD spectrum with the histogram of the diameters of a selection of the nanostructures with the corresponding SEM micrograph in the inset. The Raman and XRD suggest a monoclinic phase WO3- x (x~0.1).
