The applications of ultrathin, conductive films such as those made of graphene have many applications, but it's been thought ...

'We noticed in optical reflection measurements that light couples better to this kind of combination structure. For instance, a solar cell has less reflection and better absorption of light', Huhtio ...

Just when scientists thought they knew everything about crystals, a Northwestern University and University of Wisconsin-Madison collaboration has uncovered a hidden secret. Centrosymmetric crystals ...

Meera Chandrasekhar, a curators' teaching professor of physics and astronomy at the University of Missouri, says, "Light is a form of energy. The energy comes to the Earth from the sun through ...

“We’ve achieved a luminescent concentration ratio greater than 30 with an optical efficiency of 82-percent for blue photons,” says Berkeley Lab director Paul Alivisatos, who is also the Samsung ...

Materials get their optical properties based on how much they reflect, absorb or transmit different wavelengths (colors) of light. Usually optical coatings either reflect or transmit a given color of ...

The filter is an indispensable optical component in photography, which can change the spectral intensity distribution of the incident light or change its polarization state according to the ...

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 ...
