Study of the optical proprieties of copper oxide nanoparticles prepared by PLD method

Nano CuO thin films on glass substrates were prepared at a constant temperature of (300°C), by pulsed laser deposition (PLD) using Nd:YAG laser at 1064 nm wavelength and five deposition energies (400, 500, 600, 700 and 800 mJ) with fixed pulses (300 pulse and 6 Hz) was used on the properties of CuO films. CuO nanoparticles were deposited on glass substrates to study optical properties and formed thin films of thickness (200 nm).CuO thin flims were characterized by X-ray diffraction (XRD) measurements have shown that the polycrystalline CuO prepared at laser energies , includes optical transmittance and absorption measurements and energy gap of these films. http://dx.doi.org/10.25130/tjps.23.2018.172

Quantum Mechanical and Spectral Comparative Study of 1-p-Nitro-Benzoyl-Benzo[f]Quinolinium Methylid and 1-p-Nitrobenzoyl-2,3-Dicarbomethoxy-Pyrrolo-[1,2a]-Benzo[f]Quinoline

The quantum mechanical and spectral study of two related compounds, namely, 1-p-nitro-benzoyl-benzo[f]quinolinium methylid (BF1) and its cycloadduction derivative 1-p-nitro-benzoyl-2,3-dicarbomethoxy-pyrrolo-[1,2a]-benzo[f]quinoline (BF2) was carried out. Some electro-optical parameters in ground state were estimated by ab initio method. The solvatochromic behavior of the visible spectrum absorption band of the studied molecules in solvents with different macroscopic electro-optical proprieties was analyzed in order to estimate some microscopic molecular parameters of BF1 and BF2 in the excited state. Thus it was evidenced that, by excitation, the increase of BF1dipole moment and electric polarizability occurred while for BF2 either the increase or the decrease of these two parameters was found. The study is of practical importance for further synthesis of new derived compounds with potential applications in life sciences.
