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.

“…These parameters were obtained as result of fitting procedure for four specimens with different atomic amount of Cu dopant and are presented also in Table 3. The low values of extinction coefficient k of ZnO:Cu layers evidence the occupation of the lattice sites of ZnO by Cu ions that were confirmed by the data of XRD spectra [21,22].…”

“…Among elements available for doping, such as Al, Cu, and Ag, (Kulyk et al 2009), Ce has drawn interest in recent years due to the potential of Ce-doped ZnO films in optoelectronic applications, such as vacuum fluorescent and electroluminescent displays (Yang et al 2014(Yang et al , 2008. It is mentioned in the literature that the emission of Ce-doped films is in either the UV or the visible region (Sofiani et al 2006;Luo et al 2012).…”

Using X-ray diffraction, UV-Visible spectroscopy, XPS and photoluminescence (PL) measurements, the structural, optical and electronic properties of ZnO and Cedoped ZnO thin films were investigated; the films were deposited on glass substrates by RF reactive-magnetron sputtering and post-annealed at 300 C in an oxygen atmosphere. Under similar deposition conditions, both films crystallized into hexagonal würzite lattice structures. The pure ZnO film exhibited a c-axis preferential orientation, whereas the Cedoped exhibited an a-axis preferential orientation. The films display uniform textured surfaces with columnar-like microstructures. The UV-Vis spectra showed high transparencies of 90 % on average for both films. Band gaps of E g ¼ 3:23 eV and E g ¼ 3:27 eV for pure and Ce-doped film, respectively, were measured. The doped film spectrum was shifted to the blue as a result of the Burstein-Moss effect. The XPS spectra show that the VB edge of the doped film shifts toward lower binding energy, at $ 1.3 eV below E F , while the VB edge of the pure film is located at $ 2.0 eV below E F . Additionally, Ce 3þ and Ce 4þ ions coexist in the ZnO matrix in fractions of $ 70 and $ 30 %, respectively. The PL spectra show that both types of ions induce extra electron states that allow multiple emission peaks in the blue-green region.
