Definition

Luminescent or phosphorescent; glowing in the dark after absorbing light energy.

colloquialdescriptions

How it's used

Refers specifically to materials that store light energy and emit it slowly in the dark, rather than objects that produce light through chemical reactions or electricity. It is most commonly associated with watch hands, stickers, or novelty toys. When describing something that is naturally glowing, such as a firefly or a screen, other terms like 發光 are more appropriate.

Examples

This watch has a phosphorescent function, so it is very clear to see at night.
Is that phosphorescent necklace of yours bought in Sham Shui Po?
