Now, Eva Feldmeier and colleagues from the Technical University of Darmstadt in Germany report an organic light-emitting field-effect transistor that has colour-tunable emission. Their approach is ...

This means that each electron transition will produce a photon of a different frequency and hence a different colour. This causes line emission spectra to be produced, as shown below. This is not ...

A Japanese research team from Chiba University introduced an innovative device that combines light emission and color control using clay compounds, offering a versatile solution for ...

Researchers demonstrate a novel way to control the colour of quantum light at room temperature, unlocking new applications in ...
