Abstract

This research deals with a novel approach for the self-flux growth of Tb3Al5O12:Ce single crystal using the micro-pulling-down method. The self-flux method enables the fabrication of the crystals with excellent photoconversion and scintillation properties. Tb3Al5O12:Ce (TbAG:Ce) efficiently converts the blue light-emitting diode (LED) radiation into bright white light. The gradual change of crystal thicknesses (0.2–1 mm) allows for tuning white light temperature from cold to neutral white. The scintillation response is comparable with that of a high-quality single crystalline film counterpart with a light yield value of around 4500 photons MeV−1 under α particle excitation from 239 Pu radioisotope. This is the highest value obtained for the TbAG:Ce crystal yet.
