Wide-angle absorption of visible light from simple bilayers

Water dimer absorption of visible light

Laboratory measurements of water vapor absorption using cavity ring-down spectroscopy revealed a broad absorption at 405 nm with a quadratic dependence on water monomer concentration, a similar absorption with a linear component at 532 nm, and only linear absorption at 570 nm in the vicinity of water monomer peaks. D2O ab5 sorption is weaker and linear at 405 nm. Van’t Hoff plots constructed at...

Visible-light-driven surface reconstruction of mesoporous TiO2: toward visible-light absorption and enhanced photocatalytic activities.

The surface structure of mesoporous TiO(2) is reconstructed via a visible-light-driven reaction with benzyl alcohol molecules at mild, anaerobic conditions, which substantially extends its visible-light absorption and photocatalytic activities.

Effects of Incident Angle and Distance on Visible Light Communication

Visible Light Communication (VLC) provides wireless communication features in illumination systems. One of the key applications is to recognize the user location by indoor illuminators such as light emitting diodes. For localization of individual receivers in these systems, we usually assume that receivers and transmitters are placed in parallel. However, it is difficult to satisfy this assumpt...
