Quelques considérations sur la transmission d'énergie dans les halophosphates

J.L. Ouweltjes

Laboratoires de Recherches Philips, Eindhoven

Measurements have been made of the quantum efficiency of halophosphates activated by Sb and Mn, and of the killer effect of iron. The energy transfers between activator, sensitizer and killer ions are discussed. Possibly the greatest part of the killer effect of iron is a mere absorption.
