Optical properties of annealed Mn2+-doped ZnS nanoparticles

Heinrich Hofmann, Alke Fink, Benedikt Steitz, Yvonne Axmann

Cysteine stabilized ZnS and Mn2+-doped ZnS nanoparticles were synthesized by a wet chemical route. Using the ZnS:Mn2+ nanoparticles as seeds, silica-coated ZnS (ZnS@Si) and ZnS:Mn2+ (ZnS:Mn2+@Si) nanocomposites were formed in water by hydrolysis and conden ...

Spectral prediction model for color prints on paper with fluorescent additives

Roger Hersch

I propose a model for predicting the total reflectance of color halftones printed on paper incorporating fluorescent brighteners. The total reflectance is modeled as the additive superposition of the relative fluorescent emission and the pure reflectance o ...

Symmetry breaking in a plasmonic metamaterial at optical wavelength

Olivier Martin

We numerically study the effect of structural asymmetry in a plasmonic metamaterial made from gold nanowires. It is reported that optically inactive (i.e., optically dark) particle plasmon modes of the symmetric wire lattice are immediately coupled to the ...

Heavy metal partitioning from electronic scrap during thermal End-of-Life treatment

Christian Ludwig, Wolfram Scharnhorst

Samples of identical Printed Wiring Board Assemblies (PWBA) have been thermally treated in a Quartz Tube Reactor (QTR) in order to detect the volatility of selected heavy metals contained in electronic scrap being of environmental concern. In preparation, ...

Fast equilibration of silane/hydrogen plasmas in large area RF capacitive reactors monitored by optical emission spectroscopy

Christoph Hollenstein, Alan Howling, Laurent Fabien Hubert Sansonnens, Benjamin Strahm

The optimal plasma parameters for plasma processing, such as deposition of microcrystalline silicon from silane and hydrogen, are generally chosen in steady-state discharge conditions. However, this steady state must be reached in a short time after plasma ...

Plasma diagnostics as a tool for process optimization: the case of microcrystalline silicon deposition

Christoph Hollenstein, Alan Howling, Benjamin Strahm

Properties of thin films such as the crystallinity of silicon deposited from SiH4 - H-2 discharges are governed by the plasma composition. Therefore, it is crucial to measure the plasma composition in order to understand and optimize the deposition rate, d ...

Understanding mixed valent materials: Effects of dynamical core-hole screening in high-pressure x-ray spectroscopy

Marco Grioni

Changes in the electronic structure of Yb, a material whose valence is modified under pressure, are observed with remarkable detail in x-ray absorption and emission data measured between ambient conditions and 20 GPa. These changes are reproduced by a theo ...
