Electroluminescence is a pretty fancy sounding word,
but all it really means is a way that some things give off light
when you run electricity through them.

Electro - for electricity
luminescence - a fancy way to say light

Some of the best chemicals for making this kind of light are doped semiconductors,
which we learned before are just two kinds of chemicals mixed together.

When the electricity flows through them, the photons (which are tiny particles of light)
go shooting off of the chemicals and make it glow.
