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

The world of science is always in a state of flux, evolving and growing with each new discovery. Recently, the race to create the blackest material has seen an exciting development. A newly created ...

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 ...

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 ...

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 ...

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 ...

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 ...

This image depicts the structure of the proposed organic molecule, alongside the energy level diagrams of two-photon absorption (left side) and thermally activated delayed fluorescence (right side).

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 ...
