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.

What can Venus-like exoplanets, also known as exoVenuses, teach us about our own solar system and potentially finding life ...

This work demonstrates a novel method of manipulating the QDs’ optical properties beyond controlling their size, composition ...

This causes line emission spectra to be produced, as shown below. This is not a continuous spectrum as only light of specific frequencies and specific colours are produced. Different types of ...

Astronomers have identified a bright hydrogen emission from a galaxy in the very early universe. The surprise finding is ...

When a gas is very hot, it doesn’t emit all wavelengths of light. Hot gases don’t produce a continuous emission spectrum. Black hydrogen absorption lines are at the same wavelength as the ...

Researchers have shown that even without altering the perovskite emissive layer, incorporating polycaprolactone-silver ...

Amplified spontaneous emission is a physical phenomenon that entails the amplification of the light spontaneously emitted by ...

A set of five gas discharge tubes are arranged such that when they are touched with a Tesla coil, their characteristically colored emission spectra are seen. The Tesla coil can burn your skin on ...
