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

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.

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

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 ...

In trials using phantom and living subjects in room-temperature settings, the PTG platform showed fully passive and reliable detection of human vital signs such as temperature, heart rate and ...

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 ...

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 ...
