In this work we report an investigation of the properties of nanostructured deposits obtained from femtosecond pulsed laser deposition of CdS sintered targets. Specifically, we address the effect of laser irradiation wavelength, laser fluence and substrate temperature (from 25 to 450 ºC). The composition of the deposits was characterized using X-ray photoelectron spectroscopy (XPS), their crystallinity by Xray diffraction (XRD) and the surface morphology was studied by environmental scanning electron microscopy (ESEM) and atomic force microscopy (AFM). It has been found that the smallest nanoparticles, with an average diameter of 25 nm and a narrow size distribution, together with particulates in the range 80-120 nm, are obtained at the shortest laser wavelength of 266 nm on room temperature substrates. Deposits do not contain microscopic droplets in any of the explored conditions. 3

“…A mixture of amorphous and crystalline phases is favored by 532 nm wavelength ablation, as XRD patterns indicate [12]. A proper laser energy incident is acquired to vaporize the target and the kinetic energy in the plume can be enhanced, in this way the crystallinity could be improved, as well [8,13].…”

Cu x S thin films were grown onto soda-lime glass substrates by pulsed laser deposition at two different wavelengths: 1064 and 532 nm. X-ray diffraction, Raman and UV-vis spectroscopies were used to characterize the Cu x S films. Results are presented as a function of laser fluence. XRD patterns indicate that covellite and chalcocite phases were obtained. Raman spectra showed that chalcocite is the predominant phase in the crystalline samples. Optical band gap values are between 2.29 and 2.74 eV for ablation with 1064 nm wavelength; meanwhile, for 532 nm band gap values varied from 2.24 to 2.66 eV; which are in the range of expected values for Cu x S films. At 1064 nm and 4.4 J cm −2 sample presented the highest optical absorbance in the visible range, which corresponds to the highest thickness. These are the best growth parameters for Cu x S films in order to be used as absorber films for solar cells applications.
