Valovoisuus
Valovoisuus is a Finnish term that translates to luminescence or light emission. It broadly refers to the phenomenon where a substance emits light without being heated to a high temperature. This light emission can occur through various mechanisms, often involving the absorption of energy and its subsequent release as photons.
There are several types of valovoisuus, distinguished by the source of the energy that excites the emission.
The study of valovoisuus is important in various scientific and technological fields. It finds applications in
