| 5 | 热等静压烧结制备细晶粒 Ce,Y:SrHfO_(3) 闪烁陶瓷显示文摘Ce:SrHfO_(3)陶瓷因具有高密度和高有效原子序数,对高能射线具有很强的阻止能力。同时,Ce:SrHfO_(3)陶瓷还具有快衰减和高能量分辨率等优异的闪烁性能,引起了研究人员的广泛关注。由于传统的烧结方法难以实现非立方结构Ce:SrHfO_(3)陶瓷的透明化,本研究采用真空长时烧结和短时真空预烧结合热等静压烧结(Hot Isostatic Pressing,HIP)方法制备Ce,Y:SrHfO_(3)陶瓷。以金属氧化物和碳酸盐为原料,1200℃下煅烧8 h可以获得平均粒径为152 nm的纯相Ce,Y:SrHfO_(3)粉体。1800℃真空烧结20 h获得平均晶粒尺寸为28.6μm的不透明的Ce,Y:SrHfO_(3)陶瓷,而两步烧结法可以制备光学透过率良好的Ce,Y:SrHfO_(3)陶瓷。本研究详细分析了陶瓷致密化过程中微结构的演变,探究了预烧结温度对Ce,Y:SrHfO_(3)陶瓷密度、显微结构和光学透过率的影响。真空预烧(1500℃×2 h)结合HIP后处理(1800℃×3 h,200 MPa Ar)所获得的Ce,Y:SrHfO_(3)陶瓷在800 nm处的最高直线透过率为21.6%,平均晶粒尺寸仅为3.4μm。在X射线激发下,Ce,Y:SrHfO_(3)陶瓷在400 nm处产生Ce3+5d-4f发射峰,其XEL积分强度比商用锗酸铋(BGO)晶体高3.3倍,Ce,Y:SrHfO_(3)陶瓷在1μs门宽下的光产额约为3700 ph/MeV。良好的光学和闪烁性能可以拓宽Ce,Y:SrHfO_(3)陶瓷在闪烁探测领域的应用。 | 朱丹阳 钱康 陈肖朴 胡泽望 刘欣 李晓英 潘裕柏 MIHÓKOVÁEva NIKL Martin 李江 | 2021 | 无机材料学报2021,36,10: | 1 |

| 10 | Compositional regulation of multi-component GYGAG:Ce scintillation ceramics:Self-sintering-aid effect and afterglow suppression显示文摘(Gd,Y,Ce)_(3)(Y_(x)Ga_(1−x))_(2)GaAl_(2)O_(12)(GYGAG:Ce)scintillation ceramics with different Y excess,where x=0.005−0.08,were fabricated by the solid-state reaction method.The effects of stoichiometry on the phase composition,optical quality,and microstructure of GYGAG:Ce ceramics were analyzed.GYGAG:Ce ceramics have a pure garnet phase and obtain good in-line transmittance when x<0.04,while more Y excess leads to the creation of the secondary phase.The change of x value influences the sintering behavior of the GYGAG:Ce ceramics:The excess of Y works as the self-sintering aid and significantly reduces the sintering temperature of ceramics.When x=0.01–0.04,the X-ray excited luminescence(XEL)spectra and light yields of GYGAG:Ce ceramics are similar.The fast scintillation decay time and afterglow intensity of GYGAG:Ce ceramics show a slight decrease with increasing x value.Finally,additional 50–500 ppm MgO and 100–500 ppm CaO were introduced to the GYGAG:Ce ceramic with x=0.04,and both were found to significantly increase the fast scintillation component and reduce the afterglow intensity by two orders of magnitude to 0.01%after X-ray cut-off. | Danyang Zhu Lexiang Wu Alena Beitlerova Romana Kucerkova Weerapong Chewpraditkul Martin Nikl Jiang Li | 2023 | Journal of Advanced Ceramics2023,12,10: | 0 |
| 11 | Ce掺杂浓度对Ce,Ca:Lu_(3)Al_(5)O_(12)陶瓷闪烁性能的影响显示文摘以共沉淀纳米粉体为原料,制备不同Ce掺杂浓度的x%(摩尔分数)Ce,0.15%Ca:Lu_(3)Al_(5)O_(12)(Ce,Ca:LuAG,x=0.1~0.5)闪烁陶瓷。在分析了Ce,Ca:Lu AG陶瓷的相组成和微观结构的基础上,研究了其闪烁特性与Ce浓度的关系,包括X射线激发发射光谱、光致发光衰减、闪烁衰减、光产额及快分量、余辉。当Ce浓度超过0.3%时,光致发光衰减的加速证实了浓度猝灭的发生。Ce,Ca:LuAG陶瓷的X射线激发发射强度和光产额在Ce浓度为0.3%时达到最大值。随着Ce浓度的增加,陶瓷的余辉水平逐渐降低。最后讨论了Ce,Ca:LuAG闪烁陶瓷的制备和性能优化的策略。 | 朱丹阳 蔡金伶 BEITLEROVA Alena KUCERKOVA Romana CHEWPRADITKUL Weerapong NIKL Martin 李江 | 2024 | 硅酸盐学报2024,52,3: | 0 |
