Radio and thermoluminescence studies in CsI doped with F centers
Radioluminescence, thermoluminescence and u.v. excitation measurements in CsI additively colored crystals show a new luminescent component located at 2.5 eV. This is attributed to the radiative recombination of V k centers with F centers. Another new component at 2.72 eV is observed only under u.v....

Summary: | Radioluminescence, thermoluminescence and u.v. excitation measurements in CsI additively colored crystals show a new luminescent component located at 2.5 eV. This is attributed to the radiative recombination of
V
k
centers with F centers. Another new component at 2.72 eV is observed only under u.v. excitation of 5.14 eV. This is related to the radiative recombination of localised excitons at F
+ center sites (α band).
Des mesures de radioluminescence, thermoluminescence et d'excitation u.v. présentent dans le iodure de césium coloré additivement une nouvelle composante luminescente centrée à 2.5 eV. Nous l'attribuons à la recombinaison radiative de centres

avec des centres F. Une autre émission, située à 2.72 eV et excitée par u.v. à 5.14 eV est liée à la recombinaison radiative d'excitons localisés sur des centres F
