Researchers at The Education University of Hong Kong (EdUHK) have contributed to a study revealing that conventional theories ...

The researchers demonstrated an immediate practical application for the technology by building an organic light-emitting ...

Absorption spectroscopy is an analytical chemistry tool that can determine if a particular substance is present in a sample by measuring the intensity of the light absorbed as a function of wavelength ...

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 ...

A research group has discovered significant nonreciprocal optical absorption of LiNiPO4, referred to as the optical diode effect, in which divalent nickel (Ni2+) ions are responsible for magnetism, by ...

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 ...

A novel dye-sensitized photocatalyst developed at Science Tokyo enables the capture of long-wavelength visible light for efficient hydrogen conversion, surpassing conventional photocatalysts.

Direct laser processing of material surfaces is a powerful technique for modifying the optical and electrical properties of those materials, often through the creation of nanostructures on the surface ...

Scientists reveal new approaches to manipulating light absorption in optical resonators by different types of optical losses. Natural and humanmade physical structures all lose energy, and scientists ...

The deep-rooted beliefs that light absorption and scattering are totally harmful to fluorescence catching urge most researchers to chase a perfect window with minimal photon absorption and scattering ...
