Abstract
Luminescence and scintillation properties of single crystalline films (SCF) of Ce- and Pr-doped Y3Al5O12Y3Al5O12 (YAG) and Lu3Al5O12Lu3Al5O12 (LuAG) garnets were analysed and compared with their bulk single crystal (SC) analogues. It was shown that the main peculiarities of luminescent properties of Ce- and Pr-doped YAG and LuAG SCF are due to the absence of YAlYAl and LuAlLuAl antisite defects (AD) and to the extremely low concentration of vacancy-type defects in SCF with respect to SC. In SCF the absence of the AD-related traps results in faster energy transfer to the emission centres and accelerated scintillation response.
