“…The photoluminescence spectra of oligomers and Alq 3 , obtained at 350 nm excitation wavelength are given in Figure 17(c) and (d). The emission band with the maximum situated at 523 nm is attributed to the presence of the Alq 3 meridional stereoisomer [80]. P13 oligomer showed two emission maxima (490 and 525 nm), while P78 discloses a raw maxima at 500 nm [80], the prepared films preserving the emission properties of the start materials.…”

“…The structures realized with two organic materials are featured by a great transparency, 60% for λ > 550 nm. Absorption maxima attributed to the electronic π-π* transitions of the conjugated backbone [80] were evidenced. The absorption maxima characteristic to these materials and for the Alq 3, situated at low wavelength are hidden by the ITO substrate [81].…”

Laser techniques such as pulsed laser deposition, combinatorial pulsed laser deposition, and matrix-assisted pulsed laser evaporation were used to deposit thin films for optoelectronic applications. High-quality transparent conductor oxide films ITO, AZO, and IZO were deposited on polyethylene terephthalate by PLD, an important experimental parameter being the target-substrate distance. The TCO films present a high transparency (>95%) and a reduced electrical resistivity (5 × 10 −4 Ωcm) characteristics very useful for their integration in the flexible electronics. In x Zn 1−x O films with a compositional library were obtained by CPLD. These films are featured by a high optical transmission (>95%), the lowest resistivity (8.6 × 10 −4 Ωcm) being observed for an indium content of about 44-49 at.%. Organic heterostructures based on arylenevinylene oligomers (P78 and P13) or arylene polymers (AMC16 and AMC22) were obtained by MAPLE. In the case of ITO/P78/Alq3/Al heterostructures, a higher current value is obtained when the film thickness increases. Also, a photovoltaic effect was observed for heterostructures based on AMC16 or AMC22 deposited on ITO covered by a thin layer of PEDOT:PSS. Due to their optical and electrical properties, such organic heterostructures can be interesting for the organic photovoltaic cells (OPV) applications.

“…Figure 4 represents the SH intensity for the as-deposited films, as well as for the treated films. One can see in Figure 4 that the thermal treatment leads to a decrease of the SH signal probably due to the fact that for thin films, the surface morphology is a major parameter in the SHG capabilities, in conjuction with the film thickness and the material properties [29]. As a final aspect of the experiments regarding thin film preparation by MAPLE, we have decided to use untreated films for further LIFT experiments in order to have an optimum SH signal, as well as smother surfaces.…”
