Abstract

ABSTRACT: For neutron detection applications, we have synthesised glass phosphor materials of Ce 3+ -doped CaO–Al2 O3 –B2 O3 with consisting boron in two different forms of isotopes, enriched 10 B and 11 B, called 10 B-glass and 11 B-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 10 B- and 11 B-glasses were similar while the TL intensity of neutron-irradiated 10 B-glass was much greater than that of 11 B-glass. The TL of the 10 B-glass was observed across the neutron fluence range of 10 7 –10 12 neutrons/cm 2, and the intensity increased monotonically with neutron fluence.
