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.

基于自流生长的Tb3Al5O12：Ce单晶的新型高效闪烁和光转换材料

这项研究使用微拉法研究了一种新的方法来自生生长Tb ₃ Al ₅ O ₁₂：Ce单晶。自通量法使晶体的制造具有出色的光转换和闪烁特性。Tb ₃ Al ₅ O ₁₂：Ce（TbAG：Ce）有效地将蓝色发光二极管（LED）辐射转换为明亮的白光。晶体厚度（0.2-1 mm）的逐渐变化使白光温度从冷白调到中性白。闪烁响应可与高质量单晶膜对应物的闪烁响应相媲美，在室温下其光输出值约为4500光子MeV ^-1来自239 Pu放射性同位素的α粒子激发。这是TbAG：Ce晶体获得的最高值。
