Article: Diagnostic study of the roughness surface effect of zirconium on the third-order nonlinear-optical properties of thin films based on zinc oxide nanomaterials[show abstract] [hide abstract]
ABSTRACT: Zinc oxide (ZnO) and zirconium doped zinc oxide (ZnO:Zr) thin films were deposited by reactive chemical pulverization spray pyrolysis technique on heated glass substrates at 500 °C using zinc and zirconium chlorides as precursors. Effects of zirconium doping agent and surface roughness on the nonlinear optical properties were investigated in detail using atomic force microscopy (AFM) and third harmonic generation (THG) technique. The best value of nonlinear optical susceptibility χ(3) was obtained from the doped films with less roughness. A strong third order nonlinear optical susceptibility χ(3) = 20.12 × 10−12 (esu) of the studied films was found for the 3% doped sample.Applied Surface Science 255(8):4693-4695. · 2.10 Impact Factor
Article: Thermal stability of blends containing azo-carbazole derivatives and epoxy resin, designed for nonlinear optical applications[show abstract] [hide abstract]
ABSTRACT: Many studies have been intended to synthesize new thermally stable organic materials and polymers for nonlinear optical applications. These materials are most often guest–host systems and present some inconveniences like solvents compatibility for both the matrix and the chromophore. In the present work, we propose to use an epoxy resin as matrix for chromophores. Three blends containing an epoxy resin and azo-carbazole derivatives (either physically dispersed or chemically bound) were studied. They were prepared in form of thin films. We report their nonlinear optical properties investigated by third harmonic generation (THG) by Maker fringes technique, as well as thermal stability of these characteristics. The results show different behaviour for dispersed chromophore in a matrix and covalently bounded chromophore.Optical Materials. 31(3):501-504.
