ABSTRACT

For neutron detection applications, we have synthesised glass phosphor materials of Ce3+-doped CaO–Al2O3–B2O3 with consisting boron in two different forms of isotopes, enriched 10B and 11B, called 10B-glass and 11B-glass, respectively. For radiation detections, thermoluminescence (TL) properties of the glasses were investigated with X-ray, proton, and neutron irradiations. The TL properties of X-ray- and proton-irradiated 10B- and 11B-glasses were similar while the TL intensity of neutron-irradiated 10B-glass was much greater than that of 11B-glass. The TL of the 10B-glass was observed across the neutron fluence range of 107–1012 neutrons/cm2, and the intensity increased monotonically with neutron fluence.

通过 Ce3+ 掺杂的 CaO–Al2O3–B2O3 玻璃的热致发光检测中子

摘要

对于中子探测应用,我们合成了由两种不同同位素形式的硼组成的 Ce 3+掺杂的 CaO–Al 2 O 3 –B 2 O 3玻璃荧光粉材料,富集10 B 和11 B,称为10 B 玻璃和11 B 玻璃,分别。对于辐射检测,用 X 射线、质子和中子辐照研究了玻璃的热致发光 (TL) 特性。X 射线和质子辐照的10 B 和11 B 玻璃的 TL 特性相似,而中子辐照的10B-玻璃比11 B-玻璃大得多。在10 7 –10 12中子/cm 2的中子注量范围内观察到10 B玻璃的TL ,并且强度随中子注量单调增加。
