“…The additional presence of peaks and the fairly broad full width at half maximum (FWHM) of about 1. demonstrate that the film is of polycrystalline nature, containing some amorphous parts as well [17]. The results confirm that thin-film PLD CdS does not need a crystalline host in order to arrange itself with ordered texture [18]. This achievement is even more remarkable since the substrate was at room temperature.…”

The merger of a transparent plastic foil substrate with a semiconductor CdS film for a photonic application was realized using pulsed-laser deposition. Although plastic is not considered to be a favoured substrate material for semiconductor thin-film formation, the deposited CdS film possesses good adhesion, with a polycrystalline texture, flat surface (roughness/thickness = 0.003), and room-temperature photosensitivity with a blue-shifted peak at 2.54 eV. This work demonstrates the capability of pulsed-laser deposition to form novel heterostructures with appealing and useful technological properties such as plasticity and low weight.

“…II-VI thin films have been grown by LA on different substrates, showing that the properties are strongly affected by the substrate used. In particular, the substrate influence on the physical properties of LA-CdS thin films has been established elsewhere [10,11].…”

In this paper, we present a comparative study of photoluminescence and its relation to the structural properties of cadmium sulphide (CdS) thin films grown by chemical bath deposition (CBD), close spaced vapour transport, laser ablation (LA) and sputtering. Taking into account that the physical properties of CdS thin films depend upon the growth technique and the optimization of the deposition conditions for each technique, we show that the best crystal perfection occurs for LA-CdS films since the main photoluminescence peak at low temperature is due to bound excitons (2.53 eV). As expected, the films with the worst crystalline quality are those grown by CBD, ascertained by the photoluminescence band around 1.72 eV due to sulfur vacancies ('red band') without the corresponding exciton band. The photoluminescence results are correlated to x-ray diffraction measurements that confirm the above results.

“…The capability of changing material properties by simply changing the fluence and/or the ablation wavelength makes PLD a versatile deposition method ideally suited for prototyping. Furthermore, PLD is widely independent of substrate qualities and matching conditions (Ullrich et al, 1997). The following items show device related applications of PLD formed thin films.…”
