Sunbeams contain a lot of energy. But current technology for harvesting solar power doesn't capture as much as it could. Now, in ACS Applied Materials & Interfaces, researchers report that gold ...
How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...
Humans can only see less than 1% of the electromagnetic spectrum. Here’s why evolution may have intentionally hidden ...
WASHINGTON — Researchers have developed the first fiber laser that can produce femtosecond pulses in the visible range of the electromagnetic spectrum. Fiber lasers producing ultrashort, bright ...
LOS ANGELES, March 09, 2026 (GLOBE NEWSWIRE) -- Researchers have created a new photonic chip technology that guides light nearly as efficiently as optical fiber. By bringing fiber-like performance ...
Jan. 21 (UPI) --Scientists have discovered a molecule that can take advantage of the entire visible spectrum of sunlight. The molecule can both efficiently absorb sunlight and operate as a catalyst, ...
The world is awash with the color purple — lavender flowers, amethyst gemstones, plums, eggplants and purple emperor butterflies. But if you look closely at the visible-light portion of the ...
(PhysOrg.com) -- Monochromatic light-emitting diodes cover a large part of the visible spectrum with high effi-ciency. For blue light, nitride diodes achieve external quantum efficiencies in excess of ...
