Does glow in the dark run out?
As for if they run out: sort of. There’s nothing about the quantum transitions that damages or deforms the molecule. But, the charging process itself can gradually degrade the phosphorescent chemicals — if you expose anything to enough electricity or light it will eventually fall apart.

Tyson Butzke, a California State Parks ranger, cited the California Code of Regulations, which bans gathering of any items, even shells, from beaches. Removing a rock is even worse. It is considered “tampering with geological features.”
