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 ...

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 ...

These galaxies – some hundreds of them and called the Little Red Dots – are very red and compact, and visible only during ...

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.

Indeed, studies using oligomers with a well-defined number of repeat units show that the absorption and emission spectra redshift as the number of monomers is increased, and become ...

Moreover, discrepant degradation rates of the emitters lead to instability of the emission spectra, and rare-earth metals (e.g., Y, Ce) or toxic metals (e.g., Cd, Pb) are always used in the phosphors.

Mössbauer spectroscopy is a versatile technique that can be used to provide information in many areas of science such as Physics, Chemistry, Biology and Metallurgy. It can give very precise ...
