When studying the solar spectrum, researchers often search for specific emission lines: prominent wavelengths emitted by ions as their electrons transition from higher to lower energy levels. Emission ...

Transitions between different electronic energy levels in elements occur at unique energies and intensities, giving each element a distinctive emission spectrum. When the energy of an incident photon ...

A research team from the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences has uncovered the origins of double-peaked narrow emission-line characteristics in galactic centers ...

XES is an element-specific method primarily used to analyze the partially occupied electronic structure of materials. The technique is one of the photon-in-photon-out spectroscopies in which an ...

Over the past several decades, light sources have gradually transitioned to light-emitting diodes, or LEDs, and inorganic LEDs are now used across a wide range of applications. In parallel, organic ...
