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.

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。
