Fluorophores are chemical compounds or molecules that absorb light energy at one wavelength and re-emit it as light at a ...

Optical microscope image of a representative crystal that possesses centrosymmetry, yet shows differential absorption of circularly polarized light. The crystal is made of lithium, cobalt, selenium ...

Researchers at the University of Ottawa have made a discovery that changes what we know about light and materials. They found that engineered achiral (symmetric) materials, called achiral plasmonic ...

A research team has enhanced the titanium oxo clusters’ capacity to absorb solar energy. Their work demonstrates a successful method for modifying the behaviors of these clusters in terms of light ...

Researchers are reporting progress on the road to more efficient utilization of solar energy: They have developed an innovative light-harvesting system. In order to convert sunlight into electricity ...

Several light sources produce light across various wavelengths. While this wavelength spectrum can be useful in lighting applications, other applications require light with a restricted visible ...

VANCOUVER, British Columbia — Recently, University of British Columbia (UBC) scientists discovered a super-black material that absorbs 99% of light. The new material, which is composed of wood, could ...

It's not convincing to me either. Munroe is correct about etendue, of course, so that the best a lens can do is equivalent to having the object of focus be surrounded by the light source. But that ...

Researchers have made a discovery that changes what we know about light and materials. They found that engineered achiral (symmetric) materials, called achiral plasmonic metasurfaces, can absorb light ...
