The charge separation and excited states of antenna bacteriochlorophyll in membrane fragments of the recently discovered photosynthetic bacterium Heliobacterium chlorum were studied by absorbance-difference spectroscopy. Formation of singlet excited states of bacteriochlorophyll g with a lifetime of 200 ps or less was observed as the disappearance of the(More)
Antiglare layers for display devices feature a rough surface structure that scatters the incident light and thereby reduces the specular reflectivity of the screen. The same structure will, however, also diffuse part of the light from the phosphor layer, resulting in a degradation of image quality. The microstructure, light-scattering properties, and(More)
