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

Wildfire smoke is no longer just a short‑lived air quality problem drifting over cities for a few hazy days. New research shows that when these plumes rise high into the atmosphere, they can spawn ...

Researchers have developed a new method for light and matter interaction, paving the way for the production of ultrathin silicon solar cells. The University of California, Irvine (UC Irvine) team's ...

In a way, yes - but not because the snow itself has color. According to IFL Science, when sunlight penetrates a snowpack, the ...

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 ...

In a surprising twist, researchers have identified crystals that are symmetrical but nevertheless absorb light as if they were chiral (Science 2025, DOI: 10.1126/science.adr5478). The discovery ...

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 ...

Living bacteria embedded in silicone can absorb green LED light and re-emit it as red, offering a potential sustainable ...

Learn how spectroscopy facilitates non-invasive, real-time bio-monitoring, enhancing decision-making in healthcare, ...
