Dissimilar behavior of YAG:Ce and LuAG:Ce scintillator garnets regarding Li+ co-doping
Using a combination of experimental methods, the substitution tendencies of Li + and involved charge compensation mechanisms are determined and compared in two important similar scintillators, LuAG:Ce and YAG:Ce. The studies were performed on polycrystalline samples prepared by solid phase reactions...

+
and involved charge compensation mechanisms are determined and compared in two important similar scintillators, LuAG:Ce and YAG:Ce. The studies were performed on polycrystalline samples prepared by solid phase reactions as well as in single crystals grown by the vertical Bridgman method. The results show that Li
+
in LuAG:Ce, Li is localized mainly at Lu
3+
sites with charge compensation brought about by Ce
3+
→ Ce
4+
conversion and creation of anion vacancies. Surprisingly, unlike LuAG:Ce, Li, no evidence for Li
+
substitution at Y
3+
sites and conversion of Ce
3+
to Ce
4+
has been obtained in YAG:Ce, Li. It suggests that Li
+
goes mainly to interstitial positions and does not interact with Ce
3+
. From an application point of view, Li
+
co-doping of YAG:Ce is not efficient to improve the scintillationdecay parameters, however, it is efficient to reduce the amount of anion vacancies in both YAG and YAG:Ce.
