This paper describes the fluorescence properties of a new series of po
wder phosphors with the EU(3+) ion in the host chemicals (La,Gd)OF, (L
a,Gd)OCl, (La,Y)OF and (La,Y)OCl. Under a UV lamp, these phosphors are
found to display a bright reddish-orange colour. The measured emissio
n transitions have been characterized by determining their stimulated
emission cross sections.
