electrophosphorescent (English)

Where does "electrophosphorescent" come from?

The word electrophosphorescent is a compound blending the prefix 'electro-' with 'phosphorescent.' The latter traces back to the Ancient Greek 'phōsphóros,' meaning 'light-bearing,' which itself combines roots for 'light' and 'to bear' that extend deep into Proto-Indo-European history. Together, the term describes a modern technical process where light is emitted through the excitation of electrical energy.
