The Impact

We used a sol–gel spin coating technique to synthesize nanocomposite thin films based on zinc oxide (ZnO) loaded with silver nanoparticles (NPs). We tested these ZnO/Ag NP photocatalysts, with a thickness of about 100 nm, for the photodegradation of the indigo carmine dye solution. The study focused on the effects of Ag NPs on the ZnO matrix as well as the impact of their concentration on the photocatalytic performance of the nanocomposite. The study also highlighted the high stability of the photocatalytic performance of these nanocomposites. This work is a contribution in the search for non-toxic thin film photocatalysts that is usable under solar radiation for the treatment of contaminated wastewater. Innovation in the field of heterogeneous photocatalysis requires the use of solar resource with efficient results in terms of photocatalytic performance.

AbstractThis paper is aimed at investigating the process of photocrosslinking under Deep-UV irradiation of nanocomposite thin films doped with cobalt ferrite magnetic nanoparticles (MNPs). This material is composed of a hybrid sol–gel matrix in which MNP can be introduced with high concentrations up to 20 vol%. Deep-UV (193 nm) is not only interesting for high-resolution patterning but we also show an efficient photopolymerization pathway even in the presence of high concentration of MNPs. In this study, we demonstrate that the photocrosslinking is based on the free radical polymerization of the methacrylate functions of the hybrid precursor. This process is initiated by Titanium-oxo clusters. The impact of the nanoparticles on the photopolymerization kinetic and photopatterning is investigated. We finally show that the photosensitive nanocomposite is suitable to obtain micropatterns with sub-micron resolution, with a simple and versatile process, which opens many opportunities for fabrication of miniaturized magneto-optical devices for photonic applications.

Zinc oxide (ZnO) colloid has drawn significant attention recently due to its wide range of potential applications such as photonic crystals, solar cells, sensors, and other optical devices. In this work, low cost sol-gel spin coating technique was employed to synthesis ZnO colloid. The influences of stirring speed and post annealing temperature on the properties of ZnO colloid was investigated. The structural and optical properties of ZnO colloid was characterized using field-emission scanning electron microscopy (FESEM) and ultraviolet-visible (UV-Vis) spectrophotometer, respectively. Subsequently, Tauc method was used to estimate the optical band gap of the ZnO colloid based on the optical transmittance data. The effects of the stirring speed and post annealing temperature on the structural and optical properties of ZnO colloid are revealed and discussed in this paper. It was found that ZnO colloid prepared by the stirring speed of 500rpm and 400°C post annealing temperature demonstrates the best dispersity quality of colloid system.
