Neutron detection with glass scintillators

Enhanced emission intensity of Ce 3+ ions in Li 2 O–B 2 O 3 –Gd 2 O 3 scintillating glasses by adding carbon and Si 3 N 4 agent

“…The available technology for neutron detection is generally based on nuclear reaction, which needs high performance scintillating materials containing neutron-capture elements including 6 Li, 10 B, 155 Gd and 157 Gd [4,5]. In the 1960s, neutron detection using the fast Ce 3+ -activated silicate and borosilicate glasses was proposed by Ginther et al for the first time [6][7][8]. The temperature dependence on light yield and decay time of Ce 3+ -activated SiO 2 -Al 2 O 3 -MgO glass was subsequently investigated by Spowart et al [9,10], even the slow Tb 3+ -activated silicate glasses were also developed for thermal neutron detection [11,12].…”

“…The rare-earth (RE) doped scintillating glasses, with the considerable advantages of low-cost, largevolume, and easy shaping of elements, have reported to be one of the most promising materials for neutron detection [1][2][3]. In the 1960s, neutron detection using Ce 3+ -activated silicate and borosilicate glasses was proposed by Ginther et al for the first time [6][7][8]. Then the temperature dependence on light yield and decay time of Ce 3+ -activated SiO 2 -Al 2 O 3 -MgO glass were systematically investigated by Spowart et al [9,10], even Tb 3+ -activated silicate glasses were also developed for the detection of thermal neutron [11,12].…”

“…As a result of their thermal, mechanical and chemical durability, they are ideal for use as a variety of optical devise such as photochromatic lens for sun protection, phosphors, active laser host, scintillator and dosimetric material. Especially, 6 Liloaded silicate glass scintillator and silver activated phosphate glass dosimeter have been known as one of the commercial glasses for radiation detection [1][2][3]. However recently, number of report about development of alternative glass materials as radiation detector is smaller than those of ceramic and single crystal.…”
