Pr doped Lu3Al5O12 (Pr:LuAG) crystals were grown by the infrared convergent heating floating zone (IR-FZ) method using xenon lamps as heat sources. longer crystal of Pr:LuAG was successfully grown by this method. The optical properties of these crystal were good enough as a scintillator. They were almost same with those grown by the CZ method and the IR-FZ method using halogen lamps as heat sources. The crystalinity of the crystal grown using xenon lamps was rather better than those of these crystal. The many cracks were, however, observed in these crystal. The suppression of the crack formation was found to be very important.

采用氙灯作为热源，采用红外会聚加热浮区（IR-FZ）法生长Pr掺杂Lu3Al5O12（Pr:LuAG）晶体。通过该方法成功生长了更长的Pr:LuAG晶体。这些晶体的光学特性足以用作闪烁体。它们与使用卤素灯作为热源的CZ法和IR-FZ法生长的几乎相同。使用氙灯生长的晶体的结晶度比这些晶体的结晶度要好。然而，在这些晶体中观察到许多裂纹。发现抑制裂纹形成非常重要。
