Journal ArticleDOI
Measuring the absolute quantum efficiency of luminescent materials
TL;DR: In this paper, a measurement system and mathematical procedure are developed for determining the absolute quantum efficiency (QE) of luminescent materials, based on absorption of diffuse light within an integrating sphere, applied to fluorescent laser dyes and conventional phosphor powders.
Journal ArticleDOI
Anisotropic magnetism in field-structured composites
TL;DR: In this paper, the magnetic remanence and susceptibility increased significantly along the axis of the structuring field, and decreased slightly orthogonal to the unstructured field, relative to the magnetically soft particles.
Journal ArticleDOI
Optical properties of gold and silver nanoclusters investigated by liquid chromatography
TL;DR: In this article, the size-dependent absorbance properties of Au and Ag nanoclusters dispersed in organic solvents were investigated using high pressure liquid chromatography (HPLC) and transmission electron microscopy.
Journal ArticleDOI
Simulation of the athermal coarsening of composites structured by a biaxial field
TL;DR: In this paper, the results of a computer simulation of the evolution of structure in a two component fluid consisting of a liquid phase and a dispersed colloidal phase subjected to a uniaxial field are reported.
Journal ArticleDOI
Evolution of structure in a quiescent electrorheological fluid.
TL;DR: A real-time, two-dimensional light scattering study of the evolution of structure in a concentrated electrorheological fluid during the liquid-solid phase transition finds that after particle chaining along the electric field lines, strong light scattering lobes appear at a finite scattering wave vector orthogonal to the field lines.
