“…I 3x is the absorption-free THG signal from the fringes of the sample. The value of v RM 3 for fused silica glass equals 2.0 9 10 -22 m 2 /V 2 and 3.11 9 10 -14 esu (at k x = 1064 nm) and is reported in the literature (Chao 1971;Lee et al 2001;Kulyk et al 2010). Figure 7a, b show experimental results of the third harmonic intensity of two samples deposited on 1 mm thick quartz substrate at different substrate temperature: RT and 600°C.…”

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.

“…Figure 5 shows the PL spectrum of the undoped ZnO film, where an intense UV peak is observed at 382 nm. The UV emission is an intrinsic property of the wurtzite ZnO and is attributed to the recombination of the photoexcited holes and the electrons (i.e., exciton generation) via a radiative process (Luo et al 2012;Han et al 2005;Kulyk et al 2010). This mechanism is known as the near band edge (NBE) emission.…”

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.

Ternary compound films of ZnO-In 2 O 3 system were prepared by spray pyrolysis method. The films were deposited on heated glass substrates by pyrolytic decomposition of zinc chloride and indium chloride in distilled water with different ratio x of [Zn] In]). The phase change, chemical composition, electrical and optical properties of the Zn-In oxides were investigated over wide range of ratio x. Quasi-amorphous sub-oxide films with thickness of 200-400 nm were first obtained, the films were then annealed in Argon atmosphere at 550°C for 1 h. To optimize the physical properties of sprayed ZnO-In 2 O 3 thin films, we carry out on a systematic study of their microstructural characterization and transport properties. Continuous
