Measurements of the complex refractive index of Pd and Pt films in air and upon adsorption of H2 gas
نویسندگان
چکیده
We present complex refractive index measurements of Pd and Pt films from 700-1700nm using variable angle spectroscopic ellipsometry. Refractive index changes upon H2 gas adsorption were determined by measuring normal incidence reflection and transmission. Keywords-ellipsometry, refractive index, extinction coefficient, thin film, palladium, platinum, hydrogen, gas sensors

Hydrogen sensing by localized surface plasmon resonance in colloidal solutions of Au-WO3-Pd
Nowadays, hydrogen has attracted significant attention as a next generation clean energy source. Hydrogen is highly flammable, so detection of hydrogen gas is required. Gold nanoparticle based localized surface plasmon resonance (LSPR) is an advanced and powerful sensing technique, which is well known for its high sensitivity to surrounding refractive index change in the local environment. We p...

X-ray diffraction measurements were performed on Co?Pt1-?/Pd, Co/Pd, Co/Fe, and Co/W multilayer samples with different structures, such as Co?Pt1-? alloy layer composition ?, bilayer thickness, and number of bilayers. Multilayer samples were made by magnetron sputtering in a chamber with multi-parallel guns and a position controllable substrate. Co?Pt1-? alloy layers were deposited by cosputter...

The ability of small molecules to perturb the natural structure and dynamics of nucleic acids is intriguing and has potential applications in cancer therapeutics. This work reports the synthesis, characterization, cytotoxicity and DNA-binding studies of two cytotoxic and intercalative [M(bpy)(pyrr-dtc)]NO3 complexes (where M = Pt(II) and Pd(II), bpy = 2,2´-bipyridine and pyrr-dtc = p...
متن کاملDFT Study of Nitrous Oxide Adsorption on the Surface of Pt-Decorated Graphene
In the present study we search potential of Pt-decorated graphene (PtG) as a new nanostructure adsorbent for nitrous oxide (N2O) using density functional theory (DFT). After fully relaxation of different possible orientations of N2O-PtG complex, we distinguished two optimized configurations for this system; 1- terminal N-side of gas is oriented towards Pt so that the molec...
