“…The fundamental beam was focused on the sample using a lens with 250 mm focal length. A rotation stage with a resolution of 0.5° (model Standa 8MR180) with the mounted sample of zinc oxide thin film allowed the variation of the incidence angle [29]. After passing the sample, the transmitting filter was used to cut the pump laser beam before the photomultiplier.…”

“…All measurements were carried out using the rotational Maker fringe technique (Maker et al 1962) in the transmission scheme (Zawadzka et al 2013b(Zawadzka et al , 2015bPłóciennik et al 2015). A silica glass plate has been used as reference materials for the third harmonic generation measurements.…”

“…For each sample, the measurements of the third harmonic signal intensity as a function of the angle of incidence was performed on a total of 40 laser impulses for each angular position. Finally, the so-called Maker (Maker et al 1962;Zawadzka et al 2013bZawadzka et al , 2015b fringes were generated by rotating the sample through the range of ±60°to the normal and recorded.…”

We have investigated the structural, linear and nonlinear optical properties of high-quality MgO thin films deposited by laser ablation technique on quartz substrates. The deposition process was carried out at various temperatures of the substrates from room temperature to 600°C in order to investigate these properties of the films and their mutual influence. The structural and morphological properties of the films were investigated by X-ray diffraction. The quality of the films was improved with an increase of the substrate temperature. The linear optical properties of the films were studied by classic and timeresolved photoluminescence spectra in the broad range of the temperature form 13 to 300 K. An innovative time-resolved photoluminescence technique let us precisely measure the decay time in the real time. Results of these measurements reveal a simple exponential decay behavior typical for well oriented crystalline thin films. Presented spectra confirm high structural and linear optical quality of investigated films. The nonlinear optical properties of the films were investigated by third harmonic generation technique. Our results indicated that the substrate temperature slightly affected nonlinear optical properties and the values of third order nonlinear susceptibilities at the 600°C were found to be smaller relative to RT. All these unusual properties of MgO thin films deposited by laser ablation technique made this material very interesting for the subsequent oriented growth of the other oxide a but also for potential other optical applications.

“…Due to these exceptional properties, thin films of metallophthalocyanine have been recently intensively investigated especially by the optical methods such as absorption, ellipsometry, harmonic generation and Raman spectroscopy [6][7][8][9][10][11]. The Raman spectroscopy can be a useful tool to study various intra-and intermolecular energy transfer processes.…”

The cobalt phthalocyanine (CoPc) thin films (300 nm thick) deposited on n-type silicon substrate have been studied using micro-Raman spectroscopy, atomic force spectroscopy (AFM) and I-V measurement. The CoPc thin layers have been deposited at room temperature by the quasi-molecular beam evaporation technique. The micro-Raman spectra of CoPc thin films have been recorded in the spectral range of 1000 cm −1 to 1900 cm −1 using 488 nm excitation wavelength. Moreover, using surface Raman mapping it was possible to obtain information about polymorphic forms distribution (before and after annealing) of metallophthalocyanine (α and β form) from polarized Raman spectra. The I-V characteristics of the Au/CoPc/n-Si/Al Schottky barrier were also investigated. The obtained results showed that influence of the annealing process plays a crucial role in the ordering and electrical conductivity of the molecular structure of CoPc thin films deposited on n-type silicon substrate.
