Full textxCx:H) and hydrogenated amorphous silicon (a-Si:H) thin films have been deposited on various substrates by using plasma enhanced chemical vapour deposition (PECVD) technique. Transmission spectra of these films have been determined within UV-Visible region and the obtained data were analysed to find related physical constants such as
refractive indices, thicknesses, etc. Fourier transform infrared (FT-IR) spectrometry technique has been used to determine transmission &
reflection type spectra of these films. Obtained data were analysed to determine bond structures of the films. E®
ects of relative concentration of ethylene (C2H4) gas on thin film bond structure and on optical constants have been questioned.

Full textA major challenge to generate green energy from sunlight would be to split water which is a ubiquitous molecule to produce H$_2$. However VUV light (6.66 eV) is needed to dissociate the H-OH covalent bond. In this work we will show that it is possible to dissociate water via photo-sensitisation with UVC light, using a simple organic catalyst.Recently, ab-initio calculations predict that pyridine (Py) can act as a photo-catalyst to split water by absorption of a UV photon, following the reaction:Py-H$_2$O + h$\nu_1 \to$ Py*-H$_2$O $\to$ PyH$\bullet$ + OH$\bullet$ To test this prediction, we studied the Py-H$_2$O complex in isolated cold molecular cluster and the system trapped in cryogenic matrices. We characterized the electronic spectroscopy of the PyH$\bullet$ in the gas phase and we evidenced the reaction through UV excitation of Py-(H$_2$O) $_n$ clusters. We have evidenced that the reaction leads PyH$\bullet$ as photoproduct of the reaction. We also evidenced that the surrounding conditions play an important role in the reaction.We have demonstrated that the UV excitation of Py-water clusters leads to the formation of PyH$\bullet$, thus we have evidenced the water splitting reaction. The last step of the process, that is the regeneration of the catalyst by absorption of a second UV photon (PyH$\bullet$ + h$\nu \to$ Py + H$\bullet$) has been studied and it seems that only hot PyH$\bullet$ molecules are able to follow this channel. In the present, we are studying other aromatic molecules which are expected to lead the photochemical dissociation of water

Full textStudying the visible light-driven photoredox catalysis coupled with transition-metal complexes is of overriding importance in the development of synthetic strategy. Comparing to conventional thermal catalysis, reactions catalyzed and/ or initiated by photon energy are not only attractive for establishing a more sustainable system, but also for their unique reactivity that has previously been inaccessible. However, one issue draws our attention is that such photoredox catalytic schemes often suffer from a limited substrate scope. To develop more efficient and effective synthetic strategies applicable to broader range of substrates, it is of our interest to construct an functional and reliable instrument to identify the critical mechanistic steps that lead to low product yield. To this end, we designed a time-resolved visible-pump/ infrared-probe spectroscopic measurement technique to monitor reaction dynamics in-situ. Using our transmission infrared setup, we effectively demonstrated in-situ photoexcitation and decay process of Tris(2,2′-bipyridyl)dichlororuthenium(II) hexahydrate in deuterated acetonitrile. In addition, to optimize signal resolution, an electronic filter was installed in one of the data-collecting channels to allow for concurrent AC-coupled and DC-coupled signal recording. A series of chopper wheel experiments was conducted to assure the functionality of the system and reliability of obtained data

Full textPlasma surface modification is a widely used technique for improving the surface properties of polymers through the introduction of different functional groups. In the current research project, different methods to improve the characterization techniques of N2 and N2-H2 microwave discharge were investigated with the aim of optimizing the plasma surface process. First of all, a number of plasma parameters were measured at different process conditions. To determine the plasma parameters, optical emission spectroscopy was used not only within the well-documented UV-Visible region but also within the rarely studied infrared zone. Using infrared optical emission spectroscopy is advantageous as it eliminates the strong overlap between atomic and molecular transitions as well as the low intensity UV-Visible emission spectroscopy limitations. In the next step, the PTFE surface chemical composition was analyzed via XPS to quantify the concentrations of carbon, fluorine, and nitrogen after a plasma treatment in a N2-H2 gaseous environment. The XPS analyses were also performed after chemical derivatization to quantify the surface concentration of amino groups (%NH2) at different process conditions. The above-mentioned results were used to correlate process conditions and microwave N2-H2 discharge parameters to the chemical composition of the modified PTFE. The purpose was to determine the external plasma parameters and species present within the plasma which play a key role in the introduction of amino groups to the polymer surface. Furthermore, a mathematical model was developed using the Partial Least Squares Regression, (PLSR) using custom scripts written in MATLAB. A data set of input variables including the process conditions and plasma parameters for each experiment were generated along with the corresponding response matrix which in turn contained the surface properties of the film. The resulting database was used to build the relationship between the plasma parameters, process condition and the resulting film surface chemistry. This ultimately enabled to predict the PTFE surface chemistry from data originating from the plasma, without having to proceed to post-plasma surface characterization.
