Scintillation properties of Li6Y0.5Gd0.5(BO3)3: Ce3+ single crystal

A Comparative Study of Li6 R(BO3 )3 ; R = Gd, Lu, & Y), Single Crystals for Thermal Neutron Detection

“…A large axial temperature gradient of above 100 °C cm −1 just above the melt and a very slow pull rate were found to be optimum to control the stable single nucleation. The melt was also kept at a temperature, nearly 50°C higher than the melt temperature to control the nucleation …”

“…Single crystals of Li 6 R(BO 3 ) 3 (LRBO) doped with cerium, have been proven as a promising thermal neutron scintillator . This material contains 6 Li (natural abundance 7.4%, σ abs = 940 barns) and 10 B (natural abundance 20%, σ abs = 3835barns) having large cross‐sections for thermal neutrons and produces charged particles (α and 3 H) after the interaction with thermal neutrons . These ionising particles produce scintillation pulse in the crystal which subsequently can be processed to obtain the pulse‐height spectrum from thermal neutrons.…”

Transparent Microcomposite Films Based on a Ce-Doped Li6Gd(BO3)3 Scintillator for Radiation Detection

“…Previously, we have provided a solution to the problem of neutron−gamma discrimination for Ce-doped Gd-containing oxide scintillators in thermal neutron detection. , However, there are few investigations on the possible applications of Ce-doped Gd-containing oxide inorganic particle–polymer composite scintillators for either thermal neutron or X-ray detection. Among these oxides, Ce-doped Li 6 Gd­(BO 3 ) 3 (LGBO) has a high light yield and short decay time and potentially provides a high detection efficiency and high count rate capability for neutrons or X-rays . The light yields of single crystals under X-ray and thermal neutron irradiation are 14,000 photons/MeV and 40,000 photons/neutron, respectively. , …”
