Yes. These were originally known as Radium dials until the dangers of Radium were realised (people used to paint their teeth with Radium, to make them glow in the dark, with the result their jaws degenerated and literally fell off their skulls). You can still get radiation poising from old Radium dials, as the half-life of Radium is 1600 years.
Phosphor dials (and sometimes Tritium) replaced Radium dials and is a much safer method of making the hands of analogue clocks, watches and other dialled instruments glow in the dark. How long they glow is dependent upon the amount of light absorbed by the phosphor.
