For higher emission efficiency, the concn. (a) of Eu which is used as activator, should be 1X10<-4>-3X10<-1>. Within this range, the efficiency of emission remains essentially constant without occurrence of concn. quenching. The ratio n/m, which represents the composition of a matrix should be 1X10<-3>-7X10<-1>, for a high luminance as well as momentary emission by radiation are obtainable within this range. The phosphor is obtained, e.g., by burning in a crucible a mixt. of lanthanum fluoride, barium fluoride and barium bromide with europium oxide and chloride or bromide of an alkali element.
