When suspensions of Halobacterium halobium are exposed to bright light, the light-scattering properties of the bacteria change. This light-scattering response can produce a transmission decrease of about 1% throughout the red and near-infrared region. The action spectrum for the light-scattering response appropriately matches the absorption spectrum of bacteriorhodopsin. The response is elimina...

Different optical characterization methods were applied to a series of microcrystalline silicon thin films, either as grown, textured, or subsequently polished, mirror-like. They reveal contributions of bulk and surface light scattering effects to the phenomenon of optical absorption enhancement. The enhanced light absorption in textured layers is mainly due to a longer optical path as a result...

Sample-to-sample photon path length variations that arise due to multiple scattering can be removed by decoupling absorption and scattering effects using radiative transfer theory with a suitable set of measurements. For samples where particles both scatter and absorb light the extracted bulk absorption spectrum is not completely free from nonlinear particle effects since it is related to the a...

Light scattering in large noble gas clusters irradiated by intense laser pulses was studied and compared to absorption measurements. The scattering signal shows the presence of a peak, when the pulse width was varied, similar to one previously reported in absorption measurements. The peak of the scattering, however, occurs at a longer pulse width than for absorption. This result disagrees with ...

Analytic equations are developed for the single-scattering properties of a spherical particle embedded in an absorbing medium, which include absorption, scattering, extinction efficiencies, the scattering phase function, and the asymmetry factor. We derive absorption and scattering efficiencies by using the near field at the surface of the particle, which avoids difficulty in obtaining the exti...

Abstract We theoretically and numerically prove that under an electromagnetic plane wave with linear polarization incident normally to a single nanowire, there exists power diagram could indicate scattering properties for any system configurations, material parameters, operating wavelength. demonstrate the distinct distribution boundary in absorption, scattering, extinction generalized nanowire...

Optical characterization methods were applied to a series of microcrystalline silicon thin films and solar cells deposited by the very high frequency glow discharge technique. Bulk and surface light scattering effects were analyzed. A detailed theory for evaluation of the optical absorption coefficient a from transmittance, reflectance and absorptance ~with the help of constant photocurrent met...
