A novel dye-sensitized photocatalyst developed at Science Tokyo enables the capture of long-wavelength visible light for ...

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 ...

A bus being treated with ultraviolet light in Shanghai, China. Although types of UV light are already in use to decontaminate vehicles and indoor spaces, the wavelengths used are dangerous to people.

Solid-solution organic crystals have been brought into the quest for superior photon upconversion materials, which transform presently wasted long-wavelength light into more useful shorter wavelength ...

Researchers have synthesized a collection of nanoparticles, known as carbon dots, capable of emitting multiple wavelengths of light from a single particle. Additionally, the team discovered that the ...

There's an ultimate speed limit in the Universe: the speed of light in a vacuum, c. If you don't have any mass — whether you're a light wave (a photon), a gluon, or even a gravitational wave — that's ...
