(a) X-ray diffraction data for ITO-based ink films on PET irradiated at the fluences indicated. The PET features remain unchanged indicating no structural decomposition of the substrate. The (222) peak associated with the ITO particles is found to narrow as the incident laser fluence is increased. Application of the Scherrer equation to this feature allows calculation of the grain size and is shown in (b). The unirradiated value of the ITO particle size based on the XRD data is 23.15 nm and compares well with the average particle size employed in the manufacture of the ink (~25 nm).
