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 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 ...

Controlling a molecule is not always simple. For instance, the precise arrangement of electrons in an organic molecule determines the wavelengths of light it can absorb; this can be challenging to ...

Researchers at The Education University of Hong Kong (EdUHK) have contributed to a study revealing that conventional theories on the structure of black carbon particles—such as those emitted by ...

Highly enhanced UV absorption and light emission of monolayer WS2 through hybridization with Ti2N MXene quantum dots and g-C3N4 quantum dots This work represents a significant advancement in the field ...
