摘要：

Gadolinium gallium garnet ceramics (GGG) doped with CP3+, Pr3+ and Bi3+ have efficient luminescence. Excited by X-rays some of the investigated scintillators show an afterglow which is detrimental to an application in medical radio diagnostics. Thermoluminescent measurements between 50 K and 600 K gave results that allow to estimate the trap concentration in these materials. Only shallow traps could be found in GGG:Cr. It seems that these traps are caused by lattice defects relative to oxygen deficiency. The thermoluminescence at higher temperatures of GGG:Pr and GGG:Bi reveals deep traps which determine the afterglow in these luminescent materials.
