The single crystal scintillating optical fibers acting as the scintillators and light conductors show potential application in scintillating fiber array detectors with high spatial resolution. In this paper we report the growth of 0.2 at% Ce:Y₃Al₅O₁₂ single crystal fiber. The crystalline phase, surface morphology of the axial-section and cross-section, optical and scintillation properties of the as-grown fiber were investigated. The Ce:Y₃Al₅O₁₂ single crystal fiber has a pure YAG phase, a uniform distribution of cerium in the axial-section and cross-section surface. Emission spectrum is composed of broad bands ranging from 440 to 700 nm. In addition, the single crystal fiber has a high light yield of 26115 ± 2000 photons/MeV, low energy resolution of 9.44% @662 keV and decay time of a fast component of 78 ns and a slow component of 301 ns. The intensity ratio of fast to slow components is roughly 8:1.

作为闪烁体和光导体的单晶闪烁光纤在具有高空间分辨率的闪烁光纤阵列探测器中显示出潜在的应用。在本文中，我们报告了 0.2 at% Ce:Y ₃ Al ₅ O ₁₂单晶纤维的生长。研究了生长纤维的结晶相、轴向截面和横截面的表面形貌、光学和闪烁特性。Ce:Y ₃ Al ₅ O ₁₂单晶纤维具有纯YAG相，铈在轴向截面和截面表面均匀分布。发射光谱由 440 至 700 nm 的宽波段组成。此外，单晶光纤具有26115±2000光子/MeV的高光输出，9.44%@662 keV的低能量分辨率以及78 ns的快分量和301 ns的慢分量衰减时间。快慢组件的强度比大约为 8:1。
