Bulk synthesis of transparent and homogeneous polymeric hybrid materials with ZnO quantum dots and PMMA

In situ sol-gel polymerization is demonstrated for fabricating transparent poly(methyl methacrylate) (PMMA)-ZnO quantum dot (QD)- hybrid materials in bulk dimension. The transparent PMMA-ZnO QD hybrid materials exhibit enhanced UV-shielding effects in the ...

Opto-electronic properties of rough LP-CVD ZnO:B for use as TCO in thin-film silicon solar cells

Christophe Ballif, Sylvie Faÿ

Polycrystalline Boron-doped ZnO films deposited by low pressure chemical vapor deposition technique are developed for their use as transparent contacts for thin-film silicon solar cells. The size of the columnar grains that constitute the ZnO films is rela ...

Effects of Motion and Configural Complexity on Color Transparency Perception

Sabine Süsstrunk, Peggy Gerardin

We tested whether motion and configural complexity affect perceived transparency. A series of five coherent chromatic transformations in color space was applied across a figure: translation, convergence, shear, divergence and rotation. The stimuli consiste ...

Fiber optics opens window on stream dynamics

Marc Parlange, Nicolaas Cornelis van de Giesen

A new approach to monitoring surface waters using distributed fiber optic temperature sensing is presented, allowing resolutions of temperature of 0.01°C every meter along a fiber optic cable of up to 10,000 m in length. We illustrate the potential of this ...

Rough ZnO Layers by LP-CVD Process and their Effect in Improving Performances of Amorphous and Microcrystalline Silicon Solar Cells

Arvind Shah, Sylvie Faÿ

Doped ZnO layers deposited by low-pressure chemical vapour deposition technique have been studied for their use as transparent contact layers for thin-film silicon solar cells. Surface roughness of these ZnO layers is related to their light-scattering capa ...

Doped sol-gel materials for the production of optical fibers

The sol-gel technology offers highly interesting prospects for fiber fabrication. The main advantage is the possibility to incorporate any dopants and co-dopants soluble in a suitable solvent. Generally, these dopants are homogeneously dissolved in the mat ...

Configural and perceptual factors influencing the perception of color transparency

Peggy Gerardin

The mechanisms by which the brain represents colors are largely unknown. In addition, the large number of color phenomena in the natural world has made understanding color rather difficult. Color transparency perception, which is studied in this thesis, is ...
