Luminescence facts for kids
The dials, hands, scales and signs of aviation and navigational instruments and markings are often coated with luminescent materials in a process known as 'luminising'.
Some types of luminescence
- Chemiluminescence, the making light from a chemical reaction.
- Fluorescence, emission after higher-energy electromagnetic radiation is applied
- Phosphorescence, same cause, but emission is delayed, lasting sometimes for hours
- Electroluminescence: Light-emitting diodes (LEDs)
