A single gold nanoparticle tends to absorb within a narrow band. Much of its strongest response sits in visible wavelengths.

Sunbeams contain a lot of energy. But current technology for harvesting solar power doesn't capture as much as it could. Now, ...

Though the sun produces more energy than we would ever need on Earth, current ...

Researchers have engineered tiny gold nanospheres that can soak up almost the entire spectrum of solar energy, promising a ...

Can you briefly explain what transient absorption (TA) spectroscopy is and why it is important? Transient absorption (TA) spectroscopy is a pump-and-probe technique used to study the absorption of ...

Researchers report that gold nanospheres, named supraballs, can absorb nearly all wavelengths in sunlight — including some ...

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 ...
