“…The experimental set-up used for the thin film deposition is typical of the PLD technique and is similar with that described in ref. 18. For the needs of the deposition, an EMG 120 Lambda Physik UV TEA N 2 laser at 337.1 nm with 5 ns pulse duration and repetition rate of 20 Hz was used (pulse energy-5 mJ).…”

In present work we report the analysis of thin films and targets from new stilbazolium dye E-4-(2-(4hydroxynaphthalen-1-yl)vinyl)-1-octylquinolinium iodide (D1) deposited by Pulsed Laser Deposition (PLD) technique using high power UV TEA N 2 laser. The thin films are deposited onto substrates -KBr, 316L SS alloy, optical glass and aluminum foil. The films were characterized by FTIR spectroscopy, bright field microscopy, fluorescence microscopy and atomic force microscopy (AFM) analysis. FTIR spectroscopic analysis of thin films and target material shows small differences between deposited films and native substance. The films are found to be homogeneous by AFM results and without any cracks and droplets on the surfaces. The present study demonstrates the ability of PLD technique to provide thin films from new stilbazolium dyes with good quality when they are applied as non-linear optical (NLO) organic materials on different type of substrates.

ABSTRACT:The nonlinear optical (NLO) properties of novel styrylquinolinium dye thin films for photonic applications have been studied by the Z-scan, second harmonic generation (SHG), and third harmonic generation (THG) techniques, providing both the second-and third-order nonlinear optical parameters. The styrylquinolinium dye (E)-1-ethyl-4-(2-(4-hydroxynaphthalen-1-yl)vinyl)quinolinium bromide was synthesized by the Knoevenagel condensation, and its structure and physicochemical properties were determined by 1 H NMR, 13 C NMR, FTIR, UV−vis spectroscopy, and elemental analysis. Functional thin films were deposited by pulsed laser deposition (PLD) using UV TEA N 2 laser onto glass substrates and KCl, NaCl monocrystals at room temperature and vacuum at 10 −3 mbar/0.1 Pa. Further characterization of the films and target from native material by FTIR spectroscopy revealed that there was no difference between the deposited films and the initial material. Atomic force microscopy (AFM) and scanning electron microscopy (SEM) measurements have been also performed in order to provide information about the morphology and topology of the thin films.

Thin Nd-doped potassium gadolinium tungstate ͓KGW or KGd͑WO 4 ͒ 2 ͔ films are grown by pulsed laser deposition by ablation of a stoichiometric monocrystal target. Rutherford backscattering, x-ray diffraction, atomic force microscopy, and waveguide propagation analyses are performed. The as-grown films are optically active, as evidenced by the photoluminescence spectra centered at 1.068 m. In some of the films, fine photoluminescence spectra between Stark levels are observed.
