Unlike radioluminescent materials such as paints and pigments using radium tritium and promethium Super-LumiNova uses
link no excitant at all. Instead
link it incorporates a material known as strontium aluminate which is an
link extremely efficient phosphor that once charged will glow very brightly initially and with diminishing intensity for several hours thereafter. For strontium aluminate to be an effective phosphor it must be combined with europium a non-toxic non-radioactive chemical element.
