Strontium and europium, along with zinc oxide compounds all store ambient light, then release it over time. The advantage of the first two is the amount of light released and duration of release blow the older zinc compounds out of the water.
Everyone has had a watch with luminous hands. It was
great for perhaps and hour or two, then barely visible.
The new compounds are
BRIGHT all night long
to the night adjusted eye.
Strontium and europium are not self luminating and are not radioactive like
tritium or radium.
