Abstract
Luminescent properties of phosphors based on single-crystalline films (SCF) of Y 3Al 5O 12:Ce (YAG:Ce) and Lu 3Al 5O 12:Ce (LuAG:Ce) garnet have been analyzed in comparison with single-crystal (SC) analogues. It has been shown that the main peculiarity of luminescent properties of YAG:Ce and LuAG:Ce SCF as compared to SC is determined by the extremely low concentration of Y Al 3+ and Lu Al 3+ antisite defects (AD) in SCF. The advantages of phosphors based on YAG:Ce and LuAG:Ce SCF are caused by the absence in these SCF the additional channels for dissipation of excitation energy connected with AD and vacancy-type defects.
